I'm going to expose the runtime flag to JS for testing and modify the tests to turn it on at runtime. Expect another patch with those changes soon.

This is a static function that needs to construct a parser context. Because the enable css variables runtime flag is set at the document settings level we need to pass it in here in order to construct a parser context with the right set of flags enabled. That the existing static function doesn't do this could be considered a bug because it means that other flags like enable css regions could also be ignored.

Second patch for landing is identical except that it doesn't flip the compile-time enable flag on for chrome yet. That can happen in another patch when we're ready for it.

I'll upload a patch to fix promptly.
