Use Case
===
A scrollable overlay with kinetic scrolling enabled may be hidden with opacity: 0; and shown later (using a HWA'd transition/animation).  As such, you want to disable pointer interaction with the modal while it is hidden by using pointer-events: none;.

Problem
===
You will find that you cannot scroll the base page, because the user's pointer (finger) is still scrolling the invisible overlay.

Expected Behavior
===
That scrolling action should not be registered by the overlay, going to the next interaction-enabled element below.
