The emoji-picker is a specific piece of code as it has very strong performance requirements which are almost not found anywhere else in the app, as a result it was using various hacks to make it work decently even on old browsers.
Following our drop of Internet Explorer, and various new features in Ember and recent browsers we can now take advantage of this to reduce the amount of code needed, this rewrite most importantly does the following:
- use loading="lazy" preventing the full list of emojis to be loaded on opening
- uses InterserctionObserver to find the active section
- limits the use of native event listentes only for hover/click emojis (for performance reason we track click on the whole emoji area and delegate events), everything else is using ember events
- uses popper to position the emoji picker
- no jquery code
Meta report: https://meta.discourse.org/t/sending-many-requests-for-video-audio-upload-while-editing-post/161487
When typing in the composer we are sending a lot of unnecessary load() requests for the video/audio elements. This line was added months ago before we improved previewing/video thumbnails, which have improved things, so it is no longer required. After removing this line everything still works and no more additional requests are sent.
This fixes an issue where sometimes when composing a post and uploading a video/audio file, _loadCachedShortUrls/the uploads controller would return a full URL with origin, instead of just the URL with the host e.g. http://localhost:3000/some/video.mp4 instead of just //localhost:3000/some/video.mp4. We were prepending window.location.origin onto the URL no matter what, and since http://localhost:3000/some/video.mp4 does not match the host URL regex, we were ending up with something like http://localhost:3000http://localhost:3000/some/video.mp4 which broke composer previews. This was only noticed with a video upload in a secure upload environment.
This reverts commit 7d289a4f3e.
Now that 36bad0c31f is in and we have video previews on all platforms, the commit that's being reverted is no longer needed. In the worst case scenario, the video description is clipped under the video poster if the video aspect ratio is other than 16:9. This commit removes descriptions and the custom style for the video elements.

It's a stop gap – ideally we would generate a thumbnail for uploaded videos. For now, a bit of intentionality in the style and a pinch of context should do.
- This function now requires an explicit scope. It will never run on the entire document.
- Previously debounce was being used with an anonymous function, which means it was having no effect.
There were two constants here, `INLINE_ONEBOX_LOADING_CSS_CLASS` and
`INLINE_ONEBOX_CSS_CLASS` that were both longer than the strings they
were DRYing up: `inline-onebox-loading` and `inline-onebox`
I normally appreciate constants, but in this case it meant that we had
a lot of JS imports resulting in many more lines of code (and CPU cycles
spent figuring them out.)
It also meant we had an `.erb` file and had to invoke Ruby to create the
JS file, which meant the app was harder to port to Ember CLI.
I removed the constants. It's less DRY but faster and simpler, and
arguably the loss of DRYness is not significant as you can still search
for the `inline-onebox-loading` and `inline-onebox` strings easily if
you are refactoring.
* Remove Handlebars.SafeString usage
* DEV: Support for `import Handlebars from 'handlebars'`;
* FIX: Sprockets was broken when `node_modules` was present
By default the old version of sprockets looks for application.js
anywhere, including in a node_modules folder if this exists
(which it will when we move to Ember CLI.)
Even though `type` is an alias for `method`, we have custom logic in `/discourse/lib/ajax` that checks only `type`, and ~200 other ajax calls in the codebase already use `type` param.
When secure media is enabled and an attachment is marked as secure we want to use the full url instead of the short-url so we get the same access control post protections as secure media uploads.

* The data-orig-src attribute was not being removed from cooked
video and audio so the composer was infinitely trying to get the
URLs for them, which would never resolve to anything
* Also the code that retrieved the short URL was unscoped, and was
getting everything on the page. if running from the composer we
now scope to the preview window
* Also fixed a minor issue where the element href for the video
and audio tags was not being set when the short URL was found
