Noticed a difference in text based repaints rects between WK1 and WK2 for the following html test:
<html>
    <head>
        <script src="../../repaint/resources/text-based-repaint.js"></script>
        <style>
            body { margin: 0px; }
            #parent { position: fixed; top: 50px; left: 50px; width: 100px; height: 100px; }
            .transformed { -webkit-transform: scale3d(1, 1, 1); }
        </style>
    </head>
    <body onload="runRepaintTest()">
        <div id="parent"></div>
        <script>
            function repaintTest() {
                document.getElementById("parent").className = "transformed";
            }
        </script>
    </body>
</html>
