Non passive touch end or touch cancel listeners should not block scroll.

Ensure that touch end or touch cancel listeners don't block scroll by
removing these listeners from the touch hit test regions.

When no touch listener is encountered for TouchStart examine the touch
end/cancel listeners and determine if the touch start needs to be
dispatched non-blocking.
