@scottgonzalez - Correct, Edge does not implement an implicit capture 
on the <button> elements.

Regarding the hit testing aspects of the discussion - I do not have 
any tests or data, but I do wonder if the UA can make more 
optimizations in its hit testing than the web developer can in 
JavaScript. To put it another way, I am questioning whether a hit 
testing loop in JavaScript is really equivalent to a hit testing loop 
inside the UA.

I do agree that the same behavior that I was able to produce in my 
sample could be accomplished with hit testing in JavaScript and does 
not specifically require the enter and leave events. The code does 
seem simpler to me with the enter and leave events - but that may just
 be me.
