Can reproduce on lemmy.ml (although I can't see the logs there of course). I wanted to move to another instance to spread out more over the fediverse, but it seems my account will have to remain in existence for now.

Add the type="button" attribute to the button so that it no longer triggers the submit event on its form parent.
