Conflicts:
- `app/helpers/application_helper.rb`:
Upstream reworked how CSS classes for the document's body are computed.
Slight conflict due to glitch-soc's different theming system.
Updated as upstream did.
Conflicts:
- `spec/controllers/api/v1/timelines/tag_controller_spec.rb`:
Glitch-soc had a few extra lines in this file to account for a different
default setting. This file got replaced by
`spec/requests/api/v1/timelines/tag_spec.rb`, into which the glitch-soc
additions were moved too.
Additional changes:
- `spec/requests/api/v1/statuses/sources_spec.rb`:
Add glitch-soc-only attribute `content_type`.
