This helps reduce the amount of import cycles we have in the compose
code path following the migration to a fancier stream input.
`compose_closed_ui.initialize()` was moved further down in the
initialization order because it relies on the dropdown widget
to be defined.
Fixes#11832
This lets the user see more options than the three that appear
in the typeahead menu, and prevents them from inputting invalid
stream names.
This change replaces the input field with the dropdown, and
updates everything that referred to the classnames of the old
input field, so that they now get the data they need from the
new dropdown.
Uptil now, 1 new line was added before and 1 after a quoted message. Now
for more breathing room around a quoted message, new lines are inserted
to space it from any content before and after by at least 2 new lines.
Fixes: #23608.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
