- add `dropTargetSelector` property so that `{{koenig-editor}}` can attach drag/drop events to a larger area
- add drag/drop event handlers to `{{koenig-editor}}`
- ignore drops that occur on cards in edit mode (cards should handle drop events themselves if required)
- extract image files from the drop event and use them to create image cards
- extract image card creation from image files into a helper function
refs https://github.com/TryGhost/Ghost/issues/9623
- detect pastes that contain image files and insert a card for each, setting `payload.files` to the `File` instance grabbed from the clipboard
- update the `addComponent` hook to ensure the `payload.files` array is preserved, browsers do not allow `File` instances to be copied
- update `{{koenig-card-image}}` to look for a `payload.files` value to auto-upload it via it's internal `{{gh-uploader}}`
- NOTE: browser support for accessing image files on paste varies:
- Safari: will paste all images
- Chrome: will only paste the first image
- Firefox: will not paste any images
refs https://github.com/TryGhost/Ghost/issues/9623
- the `{{koenig-toolbar}} `didReceiveAttrs` hook was triggering an async action when the component was being destroyed so a guard is needed around the call to `set` in the `_hideToolbar` method
refs https://github.com/TryGhost/Ghost/issues/9623
- pasting inside a container card such as markdown or HTML would paste content into the card and duplicate that content outside of the card, exiting the card's edit mode in the process
- use the same "addressable" check that mobiledoc-kit's event manager uses
refs https://github.com/TryGhost/Ghost/issues/9505
- when cursor changes through the normal `cursorDidChange` or through certain programmatic changes we trigger a check to see if the cursor is out of the viewport and scroll it into view if necessary
- disable our scroll-into-view routine if the mouse button or shift key is down so that we don't interfere with default browser behaviour which works well in that situation
- for scroll-into-view at the bottom there are two slightly different methods
- if the cursor is near the bottom of the document we scroll so that the bottom padding of the editor is visible
- if the cursor is mid-document then we scroll just enough to bring the cursor into the viewport
refs https://github.com/TryGhost/Ghost/issues/9623
- match `> ` behaviour to `# ` behaviour so entering it at the beginning of an existing paragraph will convert that paragraph to a blockquote
refs https://github.com/TryGhost/Ghost/issues/9623
- pressing <kbd>Backspace</kbd> on an empty paragraph when it is the first and only section will now remove any heading or blockquote formatting that paragraph had
refs https://github.com/TryGhost/Ghost/issues/9623
- it's necessary to pass a cursor movement to `deleteCard` for card selection after the delete to work
- default to `CURSOR_AFTER` as it's the more typical direction compared to `NO_CURSOR_MOVEMENT`
refs https://github.com/TryGhost/Ghost/issues/9623
- add a `exitCursorAtTop` action to `{{koenig-editor}}` that will deselect any cards before calling the closure action
- check if the we're on a card section when pressing UP or LEFT so that the cursor being before/after the card doesn't trip up the logic
refs https://github.com/TryGhost/Ghost/issues/9623
- now that we're not creating unnecessary undo states, pasting cards with an immediate Cmd+Z works fine so we don't need to create a trailing paragraph as a partial workaround

- fixes immediate breaking of the undo stack
refs https://github.com/TryGhost/Ghost/issues/9623
- adds `parserPlugins` option with array of parser plugins that read node values and convert them when pasting
- converts `<br>` to a soft-break atom for line breaks
- removes leading newlines from text nodes to avoid leading spaces in the render output (common when pasting MD with line breaks)

- swapped html icon for code icon and added new html icon
refs https://github.com/TryGhost/Ghost/issues/9623
- fixes `Maximum call stack size exceeded` error when you paste content containing `<code>` elements and then place the cursor at the end of one of those elements
- this was occurring because the code in `inputModeDidChange()` was triggering another `inputModeDidChange() call
- use the private mobiledoc-kit methods to toggle editor state because we don't want to trigger `inputModeDidChange()` callbacks
- look at the editor state directly rather than going by what we _think_ the editor state should be based on the markers around the cursor
- fixes another subtle issue where after pasting if you placed the cursor at the end of the code format and started typing it would still be formatted as code - mobiledoc-kit has an odd behaviour where duplicate edit states for the markup are present so we have to loop over them rather than relying on a single `toggleMarkupState()` call
refs https://github.com/TryGhost/Ghost/issues/9623
- plain text that's pasted will be run through our markdown parser then mobiledoc-kit will perform it's usual rich-text paste handling on the resulting HTML
- add a <kbd>Cmd/Ctrl+V+Shift</kbd> escape valve that will skip markdown parsing so mobiledoc-kit's default plain text parsing is invoked
- will not work with IE or Edge <= 16 due to missing browser support for distinguishing plain text vs html pastes
refs https://github.com/TryGhost/Ghost/issues/9623

- match `--` and `---` and convert if followed by a space or any character respectively
- include guards to ensure that expansion doesn't occur inside code blocks
refs https://github.com/TryGhost/Ghost/issues/9623
- maintains easy reversibility by keeping text selected and toolbar shown in the same position to avoid jumping buttons when font size or other formatting changes
refs https://github.com/TryGhost/Ghost/issues/9623
- triple-click select will by default end the selection at position 0 of the following paragraph which means section-level formatting such as headers or quotes will affect the apparently unselected following paragraph
- add a guard to check for that selection situation and ensure the selection is constrained to the visibly selected text
refs https://github.com/TryGhost/Ghost/issues/9623
- keep a truthy "skip mouse move" flag around across re-triggers within the 50ms restart window to cater for slightly different mouse/selection event orders
- add a couple of guards to avoid triggering the toggle task unnecessarily
refs https://github.com/TryGhost/Ghost/issues/9505
- if there is only a single card in a document and no other text then deleting it would throw an error because we assumed there's another section to move the cursor to

refs https://github.com/TryGhost/Ghost/issues/9505
- use `ENTER` and `BACKSPACE` key commands to intercept <kbd>Enter</kbd> and <kbd>Backspace</kbd> to insert/remove blank paragraphs rather than splitting the heading when the cursor is at the beginning of a heading
refs https://github.com/TryGhost/Ghost/issues/9505

- disable `mobiledoc-kit`'s built-in link tooltip
- add `{{koenig-link-toolbar}}` component
- shows toolbar above a link when it is hovered with the mouse

- has a clickable link with the URL, opens in a new tab
- edit button switches display to the link input toolbar
- delete button removes link markup from the link
refs https://github.com/TryGhost/Ghost/issues/9505
- ensure we disable `pointer-events` on context menus when hidden so that hidden menus do not interact with the mouse
- add z-index to context menus so that they sit on top of any editor content
- add `relative` positioning to the html card content so the click overlay div doesn't expand outside of the content area
refs https://github.com/TryGhost/Ghost/issues/9505
- adjusted regexes to match a non-space group separately to a spaced group to deal with 1 or 2 chars of markup
- fixed `matchStrongStar` always triggering a markup toggle because the toggle was outside of the match conditional
refs https://github.com/TryGhost/Ghost/issues/9505
- ListItem sections have a parent rather than a prev section so we need to look for a section before the parent section when determining if the cursor is at the beginning of the doc for <kbd>Up</kbd> and <kbd>Left</kbd> key handling

- <kbd>Escape</kbd> will cancel the link input
- clicking outside the input will cancel the link input
- previously selected text will be re-selected on cancel
- if an existing link was selected (or partially selected) then pre-fill the link input with the `href`
- `X` is shown when there's a href value and clicking will clear the input
- <kbd>Enter</kbd> *with* a href value will remove all links from text that is touched by the selection and create a new link across only the selected text
- <kbd>Enter</kbd> *with no* href value will remove all links touched by the selection
- fixed toolbar tick positioning that was 8px off after change to Spirit classes
no issue
- when switching to Spirit classes the `pointer-events` styles to properly hide the hidden toolbar and `z-index` to keep the toolbar above the title input had both been missed

refs https://github.com/TryGhost/Ghost/issues/9505
- previous attempts at toggling the markup state failed because mobiledoc-kit was automatically setting the activeMarkupState after we made the replacement
- by scheduling the toggle we change the active markup state after mobiledoc has done it's thing so you can continue typing without the markdown markup being applied and without needing to insert an unexpected space
refs https://github.com/TryGhost/Ghost/issues/9505
- add `deleteCard` action to `{{koenig-editor}}` component and pass it through to the component cards
- required modifying the `_deleteCard` behaviour so that it doesn't always try to move the cursor
- use `onLeaveEdit` action from `{{koenig-card}}` in the markdown and html cards to check if their payload is empty and remove the card when exiting edit mode
- fixed `onLeaveEdit` action firing when card first rendered
refs https://github.com/TryGhost/Ghost/issues/9505
- switch toolbar `I` button to toggle `<em>` instead of `<i>`, this standardises it with the <kbd>Meta+I</kbd> shortcut

refs https://github.com/TryGhost/Ghost/issues/9311
- when using <kbd>Backspace</kbd> to delete a card the formatting (eg, heading format) on the following section would be lost
- switched to using `editor.removeSection` and a cursor change to avoid the range style deletion stripping the formatting
refs https://github.com/TryGhost/Ghost/issues/9311
- something that became apparent after adding the "<kbd>Enter</kbd> in post title adds blank paragraph" feature was that using that feature left you in a position where Backspace doesn't do what you expect - it does nothing rather than deleting the blank paragraph
- added logic to the `handleBackspaceKey` handler in `{{koenig-editor}}` to detect when backspace is pressed on a blank paragraph at the start of the doc so that we remove it then focus the title
refs https://github.com/TryGhost/Ghost/issues/9311
- the card selection in `cursorDidChange` would sometimes fail because the selection would be attempted before the newly inserted card had been pushed on to the `componentCards` array. This was reliably triggered by adding a card to a blank header section via the /-menu
- scheduling the section `afterRender` ensures that the `willRender` hook has fired and populated the `componentCards` array before the selection occurs
refs https://github.com/TryGhost/Ghost/issues/9311
- adjust our <kbd>Delete</kbd> card deletion logic to not fire if we're on a blank paragraph
- allows blank paragraphs between cards to be deleted, feels more natural

- update `{{gh-trim-focus-input}}` to inherit from `{{gh-text-input}}` and update all component uses accordingly
- standardize on using the `focus-out` action naming rather than `focusOut` for all text inputs, this is because the text input components (especially `{{gh-trim-focus-input}}`) have their own `focusOut` handler which gets overridden if consumers supply their own `focusOut` attr

refs https://github.com/TryGhost/Ghost/issues/9311
- add actions for cursor movement and pass through to card components
- `moveCursorToNextSection` deselects card and places cursor at beginning of next section, useful for caption inputs where <kbd>down arrow</kbd> or <kbd>right arrow</kbd> should move the cursor out of the input & card. Also creates an empty paragraph before moving the cursor if for some reason an empty paragraph doesn't exist after the last card in the doc
- `moveCursorToPrevSection` deselects card and places cursor at end of previous section, useful for caption inputs where <kbd>up arrow</kbd> or <kbd>left arrow</kbd> should move the cursor out of the input & card
- `addParagraphAfterCard` deselects card, creates a new paragraph after the card and moves the cursor to it. Useful for caption inputs where <kbd>enter</kbd> should have the same behaviour as if it was pressed whilst the card is selected
- modify `{{gh-uploader}}` so that it passes the FileList to it's `onStart` closure action. Useful for displaying previews when uploading images
- modify `{{koenig-card}}` toolbar display so that it can display text as well as icon buttons
- update `{{koenig-card-image}}` so that it has a full image uploader and caption input
refs https://github.com/TryGhost/Ghost/issues/9311
- add `hasEditMode` flag to the `{{koenig-card}}` component so that cards without an edit mode (eg, the image card) don't have unnecessary state changes and even listeners
- allow `mousedown` events on cards to passthrough when selecting if the target was an input or textarea so that the cursor can be placed in an input immediately instead of requiring double clicks
refs https://github.com/TryGhost/Ghost/issues/9311
- removed most of the hairy logic in `cursorDidChange` around the cursor positioning changing between head and tail within a selected card in favour of ignoring all head/tail flip flops within a selected card section and a little extra logic in our <kbd>left arrow</kbd> key handler
refs https://github.com/TryGhost/Ghost/issues/9311
- we added a guard for the caret moving from end to beginning of a card when clicking on a card whilst in edit mode in 26dd4ffb4a but it's also possible for clicks to cause the caret to move in the opposite direction
- update the guard in `cursorDidChange` to ignore the caret moving in either direction whilst a card is in edit mode
no issue

refs https://github.com/TryGhost/Ghost/issues/9311
- there was an issue where clicking inside a card whilst it was in edit mode would cause the cursor position in the editor to change from the end of a card to the beginning which would re-run our card selection routine and de-selecting the card
- add a guard to the `cursorDidChange` method that looks for an end-to-beginning move whilst a card is in edit mode and ignores it
no issue
- if the (+) button was visible and you clicked on a card to select it the cursor moved but the (+) button remained because we weren't updating the `selectedRange` property

- add a mousemove event handler that shows the (+) next to blank paragraphs when the pointer is over them
- fix sticky button when adding a card mid-document by hiding it, we get another `didReceiveAttrs` call with the new range when adding a blank paragraph so it's still shown in that situation
- fix the incorrect button position when adding a card at the bottom of the doc by re-positioning in the next runloop. Problem seems to stem from the component card being rendered after we get the new range so our position calculations are out of sync
