This is supposed to solve the "scrolling form" issue where it was difficult to implement wheel scrolling when mouse is over some widget that does not support wheel itself.

With the new change the default MouseWheel implementation simply propagates to parent and suppresses ChildMouseEvent (to maintain backward compatibility, because so far ChildMouseEvent was the only way to achieve similar behaviour).
