[Feature Queries] Enable Feature Queries on Mac

• Component: CSS
• Status: RESOLVED FIXED

[Bear Travis]

The Mac platform does not have ENABLE_CSS3_CONDITIONAL_RULES enabled, which turns on support for CSS3 feature queries.
Turning it on will also enable it in the nightlies as an experimental feature.

Add an existence test for CSS.supports. Test runs locally, so debugging this failure may take a little legwork.

Mac regression test is failing.

> LayoutTests/css3/supports-dom-api.html:10
> +    shouldBeDefined('window.CSS.supports');

I don’t understand why "window." is included here. If we were checking "window.CSS" then it would help, but for checking "CSS.supports" adding the "window." prefix doesn’t help.

Ah, yes. The test was meant to ensure that CSS exists on the window object, but it would make more sense to just test window.CSS then. Will fix this up in the next iteration, still working through the test failures.

Updated Patch

Some of the CSS productions were not properly returning values, which caused the release build to crash in certain cases.
