Merge commit '24ef8255b3f9b44cb54f49bc78fe3382a7070b1a' into glitch-soc/merge-upstream

Conflicts:
- `app/helpers/accounts_helper.rb`:
  Upstream removed a helper, textually adjacent to a glitch-soc-only one.
  Not really a conflict.
  Removed the helper as upstream did.
- `app/views/layouts/embedded.html.haml`:
  Conflicts due to theming system.
  Adapted upstream's change to our theming system.
- `app/views/statuses/_simple_status.html.haml`:
  Removed upstream, but we had local changes.
  Removed as upstream did.
