- show alerts for Edge, mobile browsers, and IE11 when accessing the editor with Koenig enabled
refs https://github.com/TryGhost/Ghost/issues/9623
- disable `contenteditable` on the main editor element when an input in a card gains focus
- Firefox chokes on inputs inside a `contenteditable` element
- use a MutationObserver inside `{{koenig-card}}` to automatically add event handlers for focus/blur events so that each card is not required to set up handlers and enable/disable content editable manually
- bump Spirit dependency
- remove `user-select: none` styling from `.form-text` for text inputs
- fixes captions and embed inputs in Safari and improves behaviour in Firefox
- add a guard around `getSelection(0)` in the `_scrollCursorIntoView()` method to avoid Safari throwing errors

- replaces hacky workaround to detect an image+figcaption inside the `imgToCard` parser plugin

refs https://github.com/TryGhost/Ghost/issues/9623
- wrap all embeds in an `<iframe>` so that their scripts are isolated (fixes FB Video)
- add `MutationObserver` implementation to adjust iframe height as embed's content is loaded
- add `noframe.js` to resize embedded iframes such as YouTube videos
no issue
- bump dependencies with non-breaking changes
- no bump of yarn.lock sub-dependencies because that bumps the version of `ember-in-viewport` to 3.0.3 that does not currently work with `ember-sticky-element`
closes https://github.com/TryGhost/Ghost/issues/9617
- bumped `ghost-spirit` to a version that doesn't use ES2015 on files that are directly included without transpilation (see related `ember-cli-cjs-transform` issue here https://github.com/rwjblue/ember-cli-cjs-transform/issues/14)
- bumped `ember-cli-ghost-spirit` to fix the `ghost-spirit` dependency version range that resulted in yarn pulling in two different versions
refs https://github.com/TryGhost/Ghost/issues/9505
- use `ember-sticky-element` to stick card icons in top left when scrolling
- pass an `headerOffset` down from the `{{gh-editor}}` component through Koenig and the card components so that it can be used for adjustments where necessary
- calculate `headerHeight` in `{{gh-editor}}` any time we change the header class
no issue
- Ember will not output the application template wrapper div in the future but it's possible to optionally enable that feature now
- fixes test harness render so that all elements are constrained to the application wrapper rather than breaking out with `position: fixed` and covering the test results
no issue
- fixes babel deprecation warning coming from `ember-element-resize-detector`
- re-created basic `resize-detector` service to wrap `element-resize-detector`
- import `element-resize-detector` directly from `npm` (includes bump to latest version)
- drop usage of jQuery selectors
