Until now, whenever the hash was updated using the `set_hash` function,
the new url was always pushed into the browser history, even if the current
hash was same as the new hash. This lead to multiple duplicate entries in
the browser history, when using the `z` hotkey to zoom to a message
repeatedly, which is very inconvenient when navigating through history.
This is now fixed by simply returning prematurely from `set_hash` if the
new hash is same as the current one. This fix will also prevent any future
features like `z` from causing duplicate browser history entries.
Fixes: #24468.
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%.
