        Geolocation needs more LayoutTests to test making callbacks to remote frames
        https://bugs.webkit.org/show_bug.cgi?id=40146

        This test is similar to callback-to-remote-context.html in that it test making a callback
        from a Geolocation object to a remote frame. In callback-to-remote-context.html, the call
        chain to the Geolocation method is started from the owning frame. In this test, however,
        the call chain is started from the remote frame.

        * fast/dom/Geolocation/callback-to-remote-context2.html: Added.
        * fast/dom/Geolocation/script-tests/callback-to-remote-context2.js: Added.
