Stop propagation and default action on WASM window pointer event

Browse Source 
The windows should not let events through to targets below (unless
they are Qt::WindowTransparentForInput, which is handled
independently). Therefore, stopPropagation and preventDefault are
now called regardless of whether the window has handled the event
or not. If the event is not handled explicitly, we still consume the
DOM event so that the windows/elements below don't get focus by
mistake.
