Patch for discussion.

Attached is a patch that fixes the described issue. We let the mouse event handler take a crack at the platform event before the context menu machinery. This is more inline with what actually happens during a right click event. Therefore, the targeted accessibility element will actually get focus as expected.

The problem I'd like feedback on is the test. testRunner.notifyDone is never called (inside finishJSTest) because the actual context menu shows and doesn't let things finish. I've looked at the non accessibility code path for testing context menus and noticed they don't actually show the context menu like we're trying to do in accessibility land. Instead, they return an array of what WOULD show. Should we be doing something similar to avoid this platform level lockup?

Any thoughts/help here would be great. Thanks!

To elaborate a bit more, this test currently works, but it simply isn't terminated correctly. Output:

stopping DumpRenderTree(pid 34298) timed out, killing it
The test ran as expected.

Again, notifyDone isn't completing as expected.

I think we want to call setTimeout before showMenu (maybe)

Sadly, doesn't help.

Confirmed the DRT function showMenu caused the exact same issue before this patch.
