When images are used which do not fill the space of the card - e.g. when
using a fullwidth card the slider is positioned to the left and doesn't

This adds a WIP for the Before/After card UI - behind an alpha flag.
It's completely missing design input and is intented to serve as a base
to work from.
no-issue
If the onUploadStart or onUploadSuccess methods error, and the error
does not contain a payload property then we recieve an opaque error
message which can be difficult to understand.
no-issue
Currently the onUploadSuccess and onUploadFailure have no way to
identify which upload has succeeded or failed other than the filename.
However the filename is not guaranteed to be unqiue, so this can cause
bugs.

- Used onmouseover because a CSS-only approach wouldn't work
- CSS can only highligh next siblings on hover, while we want to highlight previous sibling in our case

- when buttons and button-like links were mixed in a modal footer, the link did not inherit the expected button styles and if the link followed a button the two became smushed together because of missing left margins
no issue
- the upgrade button is a link rather than a button so was not triggering the modal's close behaviour
- added an `{{on "click" @close}}` handler to the link. `@close` does not preventDefault so the link's transition will still occur

Previously we were only showing a confirmation dialog if a publish action would trigger an email which was inconsistent and did not instil confidence when publishing.
- replaced old `modal-confirm-email-send` modal with the newer-style `modals/editor/confirm-publish` component
- updated to handle standard publish in addition to email publish
- updated copy
- added "error" state when attempting to send email-only post to no members
- updated publish menu `save` task to open the confirm modal when going from `draft` to `published` or `scheduled`
- underlying save with email polling moved to `_saveTask` so it can be re-used across `save` task (when not publishing) and when confirming from the modal

We now calculate whether or not a flag is enabled on the server, so this
extra check is redundant. It also means that when we promote a flag to
GA on the server this check will still take places, meaning that we need

When inserted opens a searchable gif selector, creating an image card when a gif is chosen.
Includes keyboard navigation once open:
- `Tab`/`Shift+Tab` cycles highlighted gif through search result order
- `Up` / `Down` / `Left` / `Right` moves highlight in the respective direction
- `Enter` inserts highlighted gif
For the gifs card to be activated it's necessary to add a Tenor API key (obtained freely from https://tenor.com/gifapi) via your config.production.json file:
```
...
"tenor": {
"publicReadOnlyApiKey": "YOUR_KEY"
}
}
```

We want all publish actions to trigger a confirmation modal. Currently that confirmation modal is controlled by `<GhPublishmenu>` which made it difficult to use from the route-induced publish shortcut.

By default, the uploader component was always using the `post` method to make upload calls for the files. Since some usecases like uploading media thumbnails need a different request method like `put`, this change allows overriding the request method used in upload.

- This is a proof-of-concept as there are so many ways to implement a star-rating component

- Uses the unicode star character: ★
- The inspiration is an old article from Lea Verou: https://lea.verou.me/2011/08/accessible-star-rating-widget-with-pure-css/ (minus the clever use of :not(:checked) on something that's not an input to filter-out IE)

When the gif selector is activated we want to scroll as much of the picker into view as possible.
- updated `scroll-into-view` modifier so it can work on bounding rects as well as offsets for those situations where a scroll parent is not the offset parent
- only implemented "off bottom" behavior for now as that's all we need for this use-case
- if the scroll adjustment would mean the top is cut off we readjust so that the top of the element is always visible

- `TAB` / `SHIFT+TAB` now cycle through gifs in the search return order. It means the highlight gif will not always be in the next column over but it drastically reduces the vertical scroll jumping
- `LEFT` / `RIGHT` now select the gif to the left/right that visually lines up with the top third of the currently highlighted gif and will stop at the grid edges. The result is `UP` / `DOWN` / `LEFT` / `RIGHT` act more like spatial navigation with no unexpected scroll jumps
- switching to only storing the highlighted gif and relying on indexes added to each gif by the `tenor` service when assigning to columns means that column number changes when resizing the viewport are automatically handled
refs https://github.com/TryGhost/Team/issues/1225
- added `scroll-into-view` modifier that will scroll an element into view putting it at the top or bottom of the viewport depending on which direction scroll is required
- used the `scroll-into-view` modifier to scroll the highlighted gif into view
refs https://github.com/TryGhost/Team/issues/1225
Behaviour:
- `TAB`
- highlights first gif if pressed whist search has focus
- moves highlight to right, wrapping to next row, stops at final gif
- `SHIFT+TAB`
- moves highlight to the left, wrapping to previous row
- focuses the search bar if pressed whilst first gif is highlighted
- `ENTER`
- highlights first gif if pressed whilst search has focus
- inserts the highlighted gif
- `UP`
- moves highlight up through current column
- focuses the search bar if pressed when gif in top row is highlighted
- `DOWN`
- highlights first gif if pressed whilst search has focus
- moves highlight down through current column, stops at final gif in column
- `LEFT`
- moves highlight to the left, wrapping to previous row
- focuses the search bar if pressed whilst first gif is highlighted

Re-using the existing pattern of creating an image card and having it launch an image selector was proving to have a lot of edge cases when we wanted a more streamlined in-line image selector for gifs.
- added a new `'selector'` type to card definitions
- requires a `selectorComponent` argument that is the name of a component that renders the media and handles search
- updated card components to open the selector component when respective menu item is activated
- updated slash menu to instantly trigger the selector component when the slash command matches a card and is followed by a space so that searches continue inside the selector
- added `<KoenigMediaSelector>` component that wraps the card-definition provided component and handles escape key, clicks outside of the editor, and provides a stripped down API to the child component for selecting/closing
- added `<KoenigMediaSelectorTenor>` which mostly replicates the `<GhTenor>` component but has different styling and uses the provided media selector API

Double-clicking the delete button in the confirmation modal could trigger a second attempt to delete the post/page when it had already been deleted resulting in an ugly/incomprehensible error bubbling up.
- added `{drop:true}` to the task instance so it can't be called again whilst it's currently running
- added a guard for `isDeleted` so we don't attempt to destroy an already deleted record
- added a `true` return so the button indicates a successful state rather than an error state whilst the modal is closing

It's possible to disable the Unsplash integration from the integration settings but when disabled the image selector was still available for post feature images and as an editor embed option.
- adds `isAvailable` property to card definitions, if it's set it should be a string that matches a config/setting that determines the card's availability
- unsplash card updated to use `'settings.unsplash'` as it's `isAvailable` property
- adds conditional to `<GhEditorFeatureImage>` so the Unsplash selector is only shown when enabled to bring it inline with the `<GhImageUploader>` component that was used previously for post feature images

- fixed error when tenor service is unavailable due to missing `retry` action
refs https://github.com/TryGhost/Team/issues/1219
- added optional `adjustOnResize` argument to `{{movable}}` modifier
- when the movable element's size changes (based on a `ResizeObserver` event) the passed in action is called with the element and the current x/y position
- having this handled via the `{{movable}}` modifier is needed because that's what knows about any CSS translations that are present and allows the drag position to remain in sync with any resize-related adjustments
- return value of the action is expected to be a new `{x, y}` tuple
- used `adjustOnResize` in the `<KoenigSettingsPanel>` component so that any time the settings panel grows and causes part of it to be off-screen we re-position so that the whole panel is kept on-screen
refs https://github.com/TryGhost/Team/issues/1217

When we were given a source+ref we were using that to find a theme object from the built-in list of marketplace themes and if it wasn't found redirecting to the change-theme screen. That redirect didn't need to happen because we only need the `ref` and can determine the theme name from that.
- passed `ref` through to the install modal as a data argument
- updated install modal to get theme name from passed in theme or extracted from passed in `ref` when theme is not known
- adjusted "isDefaultTheme" so it always checks against Casper rather than using the `ref: 'default'` value from the list of marketplace themes

- adds error reporting for `notifications.showAlert()` in addition to `notifications.showAPIError()` because the former is used for some handled errors but will still show the undesired red error bar
- adds `shown_to_user` tag to all reported errors. Only errors that result in the red error bar will be reported with the tag as `true`, there may still be cases where we display errors outside of the red error bar but those wouldn't make it to Sentry either, we'll need a full audit of Admin source to find those situations and handle the reporting manually
- adds `ghost` context to errors that are shown in the red bar
- `ghost_error_code` - code returned from the API or passed manually through the `notifications.showAPIError()` options argument. Will be filled in once the error message has been audited+approved
- `displayed_message` - the full error message displayed to the user. Admin combines multiple attributes from the error details so it's useful to see what we actually show

no issue
- moves disabling of scroll and pointer events into the `drag` handler so we don't inadvertently stop genuine clicks on elements inside the movable container
- adds a timeout for re-enabling pointer-events and clicks when drag finishes so we can still capture the unwanted events that would otherwise fire on mouseup
- uses a `click` event handler as that event is still fired even though we're preventing `mouseup`, fixes problems where the `pointer-events: none` on the movable container lets events through to the element behind it which could cause the movable container to be removed (eg, click event on the editor background moving a card out of edit mode)

- when a site is in private mode, design previews, the portal previews on membership, customize portal and offer pages were unable to load.
- For design and theme previews, the request to fetch preview data was failing due to cors and cookie not attached when admin and frontend have split urls.
- For portal and offer previews, there was no authentication done on private site before load, so if user opened the pages directly on them it failed to load the site.
- this change adds a new service that authenticates private site from admin as soon as user session is loaded, so previews on settings will always find the authenticated session for private sites and load correctly.
- it also updates fetch method for previews to include credentials so they are always able to fetch the site data after login

When no custom theme settings exist it's nice to have the brand settings form automatically visible when opening the design settings menu to avoid an extra click and let users make actions immediately. We don't want that behaviour when custom theme settings exist because it would hide useful context and result in extra scroll+clicks to get to the section you're interested in.
- when first rendering the menu, set the open section to `brand` if we're on the design settings index screen

We want to automatically show brand settings expanded in the design menu when the active theme has no custom theme settings, in order to do that without causing visual noise/jank we need to ensure that we have all the data we need up-front before the design menu is rendered.
- optimized `customThemeSettings` loading behaviour
- `.load()` will now only perform a fetch if settings have not previously been loaded so it can be called without causing unnecessary waits
- `.reload()` will force a clear+refetch of the settings - called by `themeManagement.activate()` after successfully changing a theme
- moved fetching of theme settings from the design menu constructor to the `settings.design` route's `model()` hook
- means the app will wait for loading to finish before showing any of the design settings screen so we can guarantee the data we need is available
- moved update of preview html from the design menu constructor to the design settings route as it's a more appropriate place to find screen setup/loading behaviour
