This was used for the very early-stage Zulip "ask for invite" form,
which was built around a stamped envelope concept. The form was
removed from Zulip a couple years ago in
bded0d9d54, but this CSS was missed in
the removal.
Given that we allow adding emoji reactions by only using the
emoji_name, we should offer the same possibility for removing
reactions to make the experience for API clients not require looking
up emoji codes.
Since this is an additional optional parameter, this also preserves
backward compatibility.
Complete, correct implementations of Zulip's emoji reactions API need
to send both emoji_code and emoji_name in order to add a reaction;
this is important for corner cases around clicking on a reaction in a
message that was first reacted to a year ago, when the emoji
name->code mappings have changed for the given code point in the
intervening time.
However, for folks building tools using the Zulip API, that corner
case is not particularly common; as a result, it makes sense to offer
an interface that allows adding a reaction by only specifying the
emoji name.
This is why the only field that needs to be required is emoji_name,
which can now be mapped to a single emoji. Both fields will be
necessary when "voting" an old reaction, but since we stil allow
specifying the two of them, these changes offer retrocompatibility.
We can now theoretically use this for any textarea
that supports our markdown (besides the compose box),
plus we keep the RTL code a bit more self-contained.
This hides the up and down arrows that appear in the year input
of the Flatpickr-provided datepicker. (This is only used in
settings for now, but the arrows will be hidden anywhere Flatpickr
is used.)
The JavaScript click handler for this feature was fragile in a way
that would break with upcoming changes to how we display the X
element. We clean this up with a replacement implementation that
should be much less fragile.
Previously, commit e5d2e95 attempted to change the styling of the user
profile pill containers to match the inputs above it. However, it used
an incorrect selector (#settings_page), resulting in all other pill
containers on settings pages being changed to match it as well
(example: User groups pill containers in Organization
settings). Additionally, its selector's specified background attribute
resulted in problems in dark mode.
To correctly style the user profile pill containers to match the other
input's styling, we apply the uneditable-input class native to
Bootstrap so that we don't need to create an entirely new selector to
style it.
Note that the .custom_user_field .pill-container selector was added so
that it could match the padding of inputs. Also, the
.custom_user_field .pill-container:focus-within selector was added
with attributes straight from Bootstrap's input:focus selectors so
that .custom_user_field .pill-container would have a blue outline
while users were typing in the input pill, just like the other inputs.
