Reading Example #8 of https://www.w3.org/TR/uievents/#click, it says ".... .... this will likely still trigger a click event  ... ...". Does that imply our current behaviour does not disobey the spec? I wonder if this behaviour is well defined in the spec.

We stop dispatching a click event when user mouse down and up on different elements.

Does that mean this bug is invalid or do we need to revise our code to be compatible?

I don't see the necessity to fire a click in this case. I mean do users really want a click when mouse down and up on different elements? I'd prefer to change it as invalid.

Please consider the behavior of other browsers, like IE, Chrome, Edge. They all fire the click.
Thanks,
