Bug 1737263 has already been backed out for other reasons. Did the performance regression go away?

Flags: needinfo?(jmuizelaar)
Flags: needinfo?(beatrice.acasandrei)

From this graph I can see that the backing out caused an improvement but Perfherder hasn't generated an alert summary for the improvement yet
