Double click is broken on Ozone X11. First, the constructor used by Ozone X11 doesn't call MouseEvent::IsRepeatedClickEvent() to check for double click events. The constructor version that takes a base::NativeEvent is what makes these checks. We can't add the check to the manual constructor because tests use it and assume the checks don't happen. Also, many other event types of have similar checks in only the base::NativeEvent constructor. Make a copy using the base::NativeEvent constructor to trigger the appropriate checks. Second, the ui::Event need to be copied before being dispatched to aura as aura may modify it. This breaks double click when the modified event is later copied and global state is set based on the modified event instead of the original event.
