If a user is editing a page and another edits it, the second user is not warned.
When the pages are finally saved, the collision is not alerted and one of the
user's changes are overwritten.
We tested with two users on this page:
As described, our test followed this:
1. First user edited page, made changes
2. Second user edited page, was not warned page was being edited
3. First user saved changes
4. Second user saved changes, was not warned of a collision, and second user
changes overwrote first user changes
Bumping severity up because this is pretty serious.
This bug apparently has to do with the theme. Users can temporarily avoid the
problem by switching themes in their UserPreferences page. Fix coming soon, it
Tickets move to docs-request so the fedora-websites component can be removed per request from Ricky.
