Looking for a filter for IE8 complex media query rules

Frameworks & Extensions

Fiddle Options

IE6(/7?) are fine with `@media screen {}` and `@media print {}`. However IE6(/7?) ignore complex media query rules after this, e.g. anything in […] is ignored in this example `@media screen, […] {}` If we had some way to make IE8 ignore complex media query rules (that also works for IE6-7), we could use it to serve a single mobile-first CSS file to all browsers while still giving IE6-8 media queried desktop styles PLZ FIND THAT WAY
