    Chromium: Call getAccessibleAtPoint() twice
    
    Chromium cannot do a hit test of web content synchronously. So what it
    does is return a guess, then fire off an async hit test. The next time
    one calls it, Chromium returns the previous async hit test result if
    the point is still within its bounds. Therefore, we need to call
    getAccessibleAtPoint() twice to be safe.
