Why do we have to do this?

[dgozman, 2014/05/29 15:28:37]

We want to hit exactly the same node as mouse event which caused context menu
did. There is a lot of logic in platform event builders, so it's better to reuse
it instead of following up with the changes.

+        dummyEvent.type = WebInputEvent::MouseDown;
+        dummyEvent.x = point.x;
+        dummyEvent.y = point.y;
+        IntPoint transformedPoint = PlatformMouseEventBuilder(m_page->mainFrame()->view(), dummyEvent).position();
         HitTestResult result(m_page->mainFrame()->view()->windowToContents(transformedPoint));
         m_page->mainFrame()->contentRenderer()->hitTest(request, result);
         Node* node = result.innerNode();
