This commit takes advantage of the `ResizeObserver` to know when dates should be re-computed, it works like this:
```
scrollable-div
-- child-enclosing-div with resize observer
---- message 1
---- message 2
---- message x
```
It also switches to bottom/height for date separators sizing, instead of bottom/top, it prevents a bug where setting the top of the first item (at the top) would cause scrollbar to move to top.
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
- Will consider a message read only one the bottom of the message has been read
- Will allow to mark a message bigger than the view port as read
- Code should be more performant as the scroll is doing less (albeit more often)
- Gives us a very precise scroll state. Problem with throttling scroll is that you could end up never getting the even where scrollTop is at 0, opening a whole range of edge cases to handle
- group writes when computing separators positions
- shows skeleton only on initial load
- forces date separator to be pinned when first message to prevent a pinned - not pinned - pinned sequence when loading more in past
- relies on `message.visible` property instead of checking `isElementInViewport`
- attempts to load next/prev messages earlier
- do not scroll to on fetch more
- hides `last visit` text while pinned
This PR is introducing glimmer usage in the chat-live-pane, for components but also for models. RestModel usage has been dropped in favor of native classes.
Other changes/additions in this PR:
sticky dates, scrolling will now keep the date separator of the current section at the top of the screen
better unread management, marking a channel as unread will correctly mark the correct message and not mark the whole channel as read. Tracking state will also now correctly return unread count and unread mentions.
adds an animation on bottom arrow
better scrolling behavior, we should now always correctly keep the scroll position while loading more
reactions are now more reactive, and will update their tooltip without needed to close/reopen it
skeleton has been improved with placeholder images and reactions
when making a reaction on the desktop message actions, the menu won't move anymore
simplify logic and stop maintaining a list of unloaded messages

1. `test()` and `render()` instead of `componentTest()`
2. Angle brackets
3. `strictEqual()`/`true()`/`false()` assertions
This removes all remaining uses of `componentTest` from core
- Note this is also tweaking the UI a little bit as we are now using links/buttons in the header as needed
- It disables the find ideal channel in drawer mode, if loading `/chat` in drawer mode it will either reopen at the last position or just stay on index
