Mouse events & disabled form controls #2368
Description
Test: http://jsbin.com/botohet/edit?js,output
A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.
I guess this is weird legacy behaviour, as it completely prevents the event, rather than stopping propagation during the bubbling phase.
Currently Chrome, Edge & Safari apply the same behaviour to all mouse events. I'd much prefer that all browsers switched Firefox's behaviour, but if it's too late to do this, the weird behaviour should probably become part of the spec.
Unfortunately Chrome & Edge do the same for pointer events, but hopefully that can be changed w3c/pointerevents#177. This was fixed for pointer events.
