feat: filter by user when interacting with the avatar (#7347)

This PR lets you filter by flag creator by interacting with the user's

feel. As such, I have also deleted the component created in a previous
PR, because it's no longer in use anywhere.

It now looks like this (when tabbed to; notice the focus ring):
