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) will implement behavior similar to WebKit, but I intend to file a follow-up bug to make Gecko behave like Blink.
