While I agree we may have to group mouse transition events together like this,
we will want them /after/ the pointer event group.

Do Edge & FF group mouse events together?

Edge doesn't do the grouping and FF does and does send the pointer event group
before mouse event group. I will change this CL to send pointer event group
first instead of this.
