When clicking on a button from the link popover, the popover gets
hidden, which pauses the editor's mutation observer until the popover is
fully faded out. This is problematic when the button in question calls
an editor command which we need to be able to undo, since the mutation
observer will still be paused during the command execution. This lets
the buttons' listeners handle the hiding of the popover themselves to
prevent this race condition.
