This commit implements all the necessary logic to create thread seamlessly. For this it relies on the same logic used for messages and generates a `staged-id`(using the format: `staged-thread-CHANNEL_ID-MESSAGE_ID` which is used to re-conciliate state client sides once the thread has been persisted on the backend.
Part of this change the client side is now always using real thread and channel objects instead of sometimes relying on a flat `threadId` or `channelId`.
This PR also brings three UX changes:
- thread starts from top
- number of buttons on message actions is dependent of the width of the enclosing container
- <kbd>shift + ArrowUp</kbd> will reply to the last message
Followup to bd5c5c4b5f,
this commit hooks up the bulk delete events for chat
messages inside the thread panel, by fanning out the
deleted message IDs based on whether they belong to
a thread or not.
Also adds a system spec to cover this case, as previously
the bulk delete event would have been broken with an incorrect
`typ` rather than `type` hash key.
- 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
