This is a Prep PR for #24426.
Removes direct dependency cycle between 'popover.js'
and overlays.js by creating popover.initialize method
called from 'ui_init.js' that calls
overlays.register_pre_open_hook(hide_all) and
overlays.register_pre_close_hook(hide_all).
Created a function call_hook that loop call all
registered hooks at the start of 'open_overlay' and
'close_overlay'.
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%.
