The MediaQueryList patch doesn't work in Safari. MediaQueryList is not available on the global scope.

I saw that addListener wasn't patched because the console didn't show zone.js as source like the other patched methods

You receive an instance of MediaQueryList when doing matchMedia('')

Sadly for whatever reason the constructor is Object :(. So I'm not sure how to access the prototype. Using __proto__ is not really the way to go, isn't it?

I guess you'd have to patch addListener and removeListener on each matchMedia(...) call, if MediaQueryList isn't public.
