In wxComboPopupEvtHandler::OnMouseEvent(), when need to relay event to drop-down button, call HandleButtonMouseEvent() directly, if possible. This is less confusing for the platform-specific wxComboCtrl implementations, and fixes issue where the drop-down button could remain in pressed state after the mouse button was lifted.
