Looks good. Not sure if you need a bug number in the commit message as well.

Nit: Could this possibly be wrapped in a block statement. I realize that there are plenty of cases like that in the code base already, but it would be slightly less prone to bugs.

Nit: Should probably use let instead of var for consistency.

Perhaps this could be folded into a function, what do you think?
