We do not want this behavior on Desktop Linux. Notice the capture related code
in DesktopWindowTreeHostX11::DispatchMouseEvent()

+TEST_F(WidgetCaptureTest, MouseEventDispatchedToRightWindow) {
   MouseEventTrackingWidget widget1;
   Widget::InitParams params1 =
       CreateParams(views::Widget::InitParams::TYPE_WINDOW);
