The spec for matchMedia is not very clear on two points:

1) When exactly "the associated media query list changes in evaluation".

2) What should happen for display:none iframes.

In practice, all three of Firefox, Safari, and Chrome have different 
behaviors on the attached testcase, though I'm about to make some 
changes to Firefox that will likely make it match Safari on this one 
specific testcase, more or less by accident.
