iPad: after tapping on a mention, there is no back button

In this video you can see the problem. First I tap on the mention for equinox. Then there is no back button so there is no way to get back to the room.

When I tap on benpa’s avatar, it correctly shows the back button.


Also on both iPad and iPhone when you tap a mention, the pit avatar is cut off but when you tap on a user it works normally.

No source file or test is named. Reproduce the mention and avatar flows on iPad and iPhone, compare their navigation and avatar presentation, and trace the room-to-profile entry point; done means mentions provide a back path and avatars are not cut off on either device.
