FEATURE: Don't display muted/ignored users under "who liked" (PR #10084)

Previously, if you clicked on the heart icon below a post it would show you the avatar for a user even if you ignored or muted them.

This commit will instead display a (?) icon. The count of likes will remain correct, but you needn’t be reminded of the person you preferred not to see.


I was thinking a blank grey circle would be better than a ? icon which might call attention to it, LIKE THE RIDDLER
