        [Qt] fast/events/fire-mousedown-while-pressing-mouse-button.html failing
        https://bugs.webkit.org/show_bug.cgi?id=58863

        Fixes an issue where a platform mouse event corresponding to mouse button A
        may be associated with the wrong WebCore mouse button when the event occurs
        while pressing and holding a mouse button B, where A != B.

        For example, a person clicks the middle mouse button while pressing and holding
        the left mouse button. Then we dispatch the following DOM events: mouse down for
        left button, mouse down for left button, mouse up for left button. But, we should
        have dispatched: mouse down for left button, mouse down for middle button, mouse up
        for middle button.

        * platform/qt/PlatformMouseEventQt.cpp:
        (WebCore::mouseEventTypeAndMouseButtonFromQEvent): Added.
        (WebCore::PlatformMouseEvent::PlatformMouseEvent): Modified to call mouseEventTypeAndMouseButtonFromQEvent()
        to determine the WebCore mouse event type and button from the platform-specific event.
