[pointerevents] Define behavior for wheel event group when the initial target is mutated (#597)

dlrobertson has just created a new issue for https://github.com/w3c/pointerevents:

== Define behavior for wheel event group when the initial target is mutated ==
Browsers currently differ on what should happen when the target of a wheel event group is mutated. For example, when the target of a wheel event group is removed:

 - Blink will retarget once and all following events will be sent to the same element
 - WebKit will send each following event to the topmost target

The initial work to add wheel event groups to Gecko ([bug 1168182](https://bugzilla.mozilla.org/show_bug.cgi?id=1168182)) will implement behavior similar to WebKit, but I intend to file a follow-up bug to make Gecko behave like Blink.
