Session Replay - Are icons not possible to unmask?

Hello! I have been recently tinkering around with Session Replay, with full privacy settings, unmasking information that is not sensitive and I have been running into this issue: no matter which tags I use, I cannot seem to be able to unmask icons, always getting a square on the replay, instead of the icon. So this has left me wonder if it is actually possible to unmask icons or if I am missing something. Is there something else I should be doing here?
