Thx for the PR, very much appreciated. Will pick it into the v3 branch and release a new version "soonish" (aka tomorrow if nothing goes wrong)

[rejas]

By the way: Do you feel adventourous enough to write a test for this so the code coverage goes up again?

[rejas]

Ok, "soonish" came quicker than I thought :-) Hope v3.11.8 helps your project a little!

Hah thanks, I ended manually mutating the minified output, and given we only rebuild modernizr every six months or so it'll come in handy for when I would have inevitably forgotten to mutate the minified output in another six months
