        Fix chromium iframe shims.  Add another test case to the
        iframes-shims test.  After r53637, the plugin widget doesn't get
        moved every paint.  This used to hide the bug that if an iframe
        gets added, the plugin's cutout rectangles don't get updated until
        a layout happens.
