Previously, exact matches could be pushed off the typeahead list in the
case where there were more prefix matches that happened to rank first,
which is confusing to the user: if an emoji, for instance, falls into
this category, it will never show up in typeahead, which is easy to
confuse with the emoji not existing.
This isn't a perfect fix — there are still cases where it's hard to find
emojis because the prefix-space is very crowded, but it does fix a
category of surprising and frustrating behaviour.
This doesn't come completely without downside - it means that the exact
match emoji will jump to the front of the list, which changes what is
currently conceptually a "filtering" operation to a "filtering and
sorting" operation, but it seems on the whole to be a more ideal
experience. This is particularly notable in the non-typeahead emoji
picker, which uses the same codepath, but this change seems somewhat
desirable even there, since it allows the user to type the name of an
emoji and press enter and have that emoji show up, without having to
visually confirm that they aren't inadvertently selecting a
prefix-matching emoji.
A better solution to this in the long term might be ordering emoji
results by shortest-first as a tiebreaker for alphabetical ordering,
since that should provide the same behaviour while keeping the mental
model as "filtering" (since the sort order won't change as the user
types), but this seems like a reasonable first pass, and changing to
shortest-first ordering after making this change won't break any muscle
memory for existing users.
We manually trigger a re-render of RT after a stream is muted
to update the list of topic in RT for the active filter.
This fixes the bug that RT doesn't update correctly
after a stream is muted.
If user is in private message narrow, we reduce height of stream
list to allow height for pm list in the left sidebar. We need
to recalculate it when moving out of pm narrow and moving in
rt narrow.
When idle, we try to backfill messages and in the end reselect
the closest message in the list, which can be a unread message
if present.
When recent topics is open, we can backfill messages; but
shouldn't select the message_id otherwise it will mark the
message as read if the message is unread while triggering
`message_selected.zulip`.
User can go from recent topics to stream / topic narrow via various
means, but all go through narrow.activate, hence we make sure all the
state changes we do in recent_topics.hide are actually applied when we
hide recent topics and go to another narrow.
This fixes the bug that narrowing from left sidebar to a stream
takes user to the top of the narrow.
We land user on the first row of the table instead of the search
box because here user can access hotkeys like `w`, `q`, `/`, etc,
which will not be directly available if user is focused in
recent topics search box.
For tests:
We set focus to search by default to avoid mocking a lot of
table html for getting the tests passing.
Previously the filter would be reset every time the page was
refreshed. This commit adds persistence via localstorage, the tests
follow the pattern used in tests for drafts.
Fixes: #15676.
Go to Recent Topics on "#", no hash and "#recent_topics".
Go to Recent Topics as the last destination for escape key.
Map `a` key to All messages and change its hash to
`#all_messages`.
