Weblate: Stored HTML injection in editor search preview
### Impact
Weblate's live search preview renders unit `source` and `context` as HTML without escaping. Any contributor whose content reaches those fields stores HTML and CSS that runs inside the authenticated editor of every user who runs a matching search.
