- the <code>`</code> key on German keyboard layouts is a dead key and so does not trigger the typical keyboard events our editor relies on
- added custom keyboard event listeners to watch for specific keyboard event sequences triggered by using the dead key + spacebar to insert a <code>`</code>
- trigger text input handlers when we detect a <code>`</code> insertion
- Linux unfortunately does not trigger events that can be used to track the sequence so this will not work there although it is easier to set up keyboard layouts without dead keys on Linux
- moved modifier key tracking into global event handlers from ember event handlers
- reduce confusion from duplicated event handling
- allows modifier key handlers to fire when keys are pressed without the editor element having focus
no issue
- added `onUploadStart` action to `{{gh-uploader}}` that is triggered when individual files start uploading
- will not be triggered for any files that fail client-side validation
- changed `{{koenig-card-gallery}}` to only add images to the local gallery display when the uploader starts an upload
no issue
- moved all payload building into single function
- only put fully valid images into mobiledoc
- extracted image data reading and width/height reading into a separate function
- fixed re-ordering when deleting an image
no issue
- stubbed `ghostPaths` service did not have the expected `ghostPaths.assetRoot` property that the `gh-profile-image` component started calling `.replace` on in adb0508d2f

- removed 1px white border on embed card click overlay so that it doesn't cover borders used by certain embeds such as Instagram and Facebook posts
no issue
- dropping IE11 support meant that babel/uglifyjs was able to be clever and inline the image URLs variables directly into the template strings which was then breaking the fingerprint asset rewriting resulting in files having hashes but file references in the JS not having the hash
- removing use of template strings to build the default image URLs prevents the inlining behaviour, letting the asset fingerprint plugin do it's thing correctly

- `formatMarkdown` was previously changed to return a SafeString but that meant any direct usage of the helper had to account for not dealing with a basic String type
- changed `formatMarkdown` to return a basic String
- modified helper usage of `{{sanitize-html}}` to use triple-curlies

- adds `routes.yaml` upload using the same UI as the `redirects.json` upload
- upload: `POST /settings/routes/yaml/`
- download: `GET /settings/routes/yaml/`

- fixed Card menu plus icon's rounded edges
- decreased link toolbar appearance delay
- changing 'H'/'h' toolbar mapping to 'H2'/'H3' and harmonized title font size

- the "paste url on a selection to make it a link" feature from the main editor was missing in caption inputs
- copied functionality across (shared functionality needs extracting at some point)

- `clean-basic-html` was being overzealous with it's empty element removal, often contenteditable (especially when pasting) will result in HTML such as `<span> </span>` which was being completely removed
- if an empty element has any spaces in it, replace the element with a textNode containing a single space

- focus was not being returned to the editor after the Unsplash modal was closed so although the image card looked selected the editor was not responding to any key commands
refs https://github.com/TryGhost/Ghost/issues/9724
- mobiledoc-kit's `key.isPrintable()` returns true for <kbd>Enter</kbd> but in this instance we don't want to capture newlines as printable chars
- swapped insertion of `event.key` for `key.toString()` for better handling of named keys that output characters (eg. when `event.key` === `Enter` which prints `\n`)

- we call `koenig.cleanup` when setting a post in the editor controller but the call will happen before `componentCards` has been populated so none of our "delete if empty" routines were being run
- calls to `.cleanup` now schedule the cleanup after the next editor render which should mean cards are populated before we try to remove them
refs https://github.com/TryGhost/Ghost/issues/9724
- standardised `{{gh-unsplash}}` actions and action arguments to better represent a generic "image source"
- added `{{gh-unsplash searchTerm="ghosts"}}` parameter
- added `payload` param to `card` definitions used for plus/slash menus so that default payload params can be passed to cards
- added a concept of "image selectors" to image card
- if a `payload.imageSelector` param is received by the card it will look it up in it's list of known selectors and display the appropriate image selection component
- if the card was created with an image selector param and the image selector is closed without selecting an image then the card will be removed
- delete image cards during cleanup if they were created via selector but have no src

- extract html sanitisation into a Koenig helper `{{sanitise-html}}` (all markdown handling will eventually move into Koenig too)
- render sanitised html in the html card
no issue
- re-org of the text-expansions code meant that the smart hyphens expansion was being picked up before the divider card expansion and blocking it
refs https://github.com/TryGhost/Ghost/issues/9724
- add a `data-kg-allow-clickthrough` attribute so that it's possible to explicitly allow non-input elements to be clicked immediately when clicking on a card
