Polyfilled matchMedia never matches float "max-width" queries

[TxHawks]

Whenever passing a float as the value of a max-width query, matches returns false even when the test should pass. Tested this with both px and em based queries.

Expected behavior:

// After polyfilling matchMedia
window.innerWidth = 700;
window.outerWidth = 700;

window.matchMedia('(max-width: 2.5em)').matches; // => true

Actual behavior:

// After polyfilling matchMedia
window.innerWidth = 700;
window.outerWidth = 700;

window.matchMedia('(max-width: 2.5em)').matches; // => false
window.matchMedia('(max-width: 3em)').matches; // => true

To add to the above, float min-width queries always match

Was there any movement on this?
