Jeff, looks like bug 1498070 regressed something here. Maybe the same as bug 1503813?

Well this change is going to ride into Release with 64, unfortunately.

I'll assume that means no chance of reverting it and mark this as wontfix for 64.

Happy to take a patch in nightly or even in beta 66 for this.
I'm marking it fix-optional to remove it from weekly triage.
