 | <p>Bug <a href="http://webkit.org/b/109230">109230</a>: REGRESSION(r130089): Scrollbar thumb no longer re-rendered on hover</p> | 
 | <p>For this test to pass, the below box should be green (in DumpRenderTree).<br> | 
 | Interactively, the whole box should turn green on mouseover, even if not over the scrollbar thumb.</p> | 
 | <div id="scrollable"> | 
 |     <div id="content"></div> | 
 | </div> | 
 | </body> |
