        [Chromium] Hulu popups are blocked
        https://bugs.webkit.org/show_bug.cgi?id=44572

        We were blocking popups created by Flash Player because we were never
        setting the UserGestureIndicator for events.  Most WebKit ports handle
        events through EventHandler, but Chromium is special (for some unknown
        reason) and dispatches events directly.  That means Chromium misses out
        on some of the work done by EventHandler, including setting the
        UserGestureIndicator.

        I suspect this is covered by an existing LayoutTest, but I don't have
        the ability to run the Chromium LayoutTests on this machine.  :(
