Summary:
Ref T8980. This isn't 100% coverage but should be pretty much all of the common ones.
These feel a touch iffy to me at first glance so I didn't go crazy trying to hunt all of them down. I have some other plans for them so maybe they'll feel better by the end of it.
Test Plan: Hovered over author, reviewers, blocked tasks, projects, etc.
