At times, it might get confusing for users who are on
slow connections if their messages has not been sent
even after 5s. Including a spinner that will only show
up after 5 seconds has elapsed will keep user informed
about their slow connection.
5s is set as minimum time because showing up a spinner
before than might be distracting for users on normal
connections.
Fixes: #19328.
Since the message time of locally echoed messages were not displayed
and their width was restricted by `notvisible` CSS class, it
resulted in width available to message text changing after the message
was successfully sent and the time was displayed.
To fix this, we just try to set opacity of the message time to 0
for locally echoed messages.
Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.
