Description Mihnea Ovidenie 2013-08-01 00:13:34 PDT
With the following test case:
<!DOCTYPE html>
<html>
    <head>
        <style>
            #article { -webkit-flow-into: flow; width: 100px; height: 100px; }
            #region { -webkit-flow-from: flow; position: fixed; }
            #scroller { position: absolute; top: 1000px;}
        </style>
    </head>
    <body>
        <div id="article">AAAAA</div>
        <div id="region"></div>
        <div id="scroller">Test</div>
    </body>
</html>

If one scrolls up&&down the document, the content flowed in region is painted incorrectly. Adding background-color or border to the region fixes the problem.
