I am pretty sure this is the same problem as bug 1510447, I'm about to submit a fix.

It's a bit hard to analyze, because in the interim between the regression and the proposed fix we landed bug 1509974, which altered the baseline. Still, it looks like we got a drop in [1], which is where bug 1510447 landed. Resolving fixed.
