I'm not entirely convinced that this is caused by the addon change. The patch in question added a few interventions and removed a few interventions, but there was no change to the global JS. Looking at the future development of that graph, it sometimes bumps up and down with roughly the same value.

Looking at other pushes in the same area, I noticed bug 1341937, which probably could have an impact here. However, since the change is so low and appears to be within the usual fluctuations, I'll close this as wontfix for now.
