Test case

As of r248819 (fix for https://bugs.webkit.org/show_bug.cgi?id=200204) we now correctly reset the touch-action property when crossing frame boundaries. However, if you interact with a frame, its touch-action setting might clash with the one set with the parent frame. For instance, with the attached test case, panning with a downward gesture will scroll the outer document even though it has `touch-action: none` set.
