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%.
