3% regression in rendering.mobile at 584567:584585

Project Member Reported by majidvp@chromium.org, Aug 22 
It is a amall regression and all other tests in the same benchmark has improved significantly at the same time so it seems to be an overall improvement. 

Most likely we can close this as WONTFIX but it is a good idea to see if we can identify the root cause to be sure.
