Heart given by mistake cannot be erased?

My mouse fell and the button press put a :heartbeat: on


Now I can’t “unlike” it. Why is it just in this post (it works elsewhere), and can I undo it? Thanks @vchuravy

I encounter this same bug sometimes. It seems to happen intermittently and in a non-deterministic manner.

I think you gotta click on the “heart” part not the number part

I know. Thanks.
