    wayland: Check serial for activation if no surface is provided
    
    Having a "requester" surface helps with accuracy (e.g. ensuring the
    pointer is still within coordinates, besides the token serial still
    remaining valid). In the case we don't have one, still check the
    serial so that we know no other button presses/etc happened in between
    and activate the window if none happened.
