Can't be that fix, it's a change to a reftest fuzziness. No code changed there.

Sorry Robert, I must have miss-read the graph. Can I ask you to just point the problem? This regression's descriptions is particularly for your bug. Normal we have to close this as invalid and open another one for a different culprit. Otherwise the data in the description doesn't match and miss-leads.
