Putting your own mention in your name and clicking the mention jumps the usercard to a weird position

This is more of a ux issue than a bug issue so I put it in UX.

To reproduce: Click on a place where your usercard is displayed. Then, click the mention. Your username will then be displayed in a weird postion.
