HTML file highlighting the problem

If an @region rule is used inside a media query, it is ignored. Other rules/declarations in the media query are properly applied.

Reproduction steps:

1. Open attached file in WebKit nightly

Expected result
You should see a green text with a green outline (the green color of the text is set via @region inside a media query, the green color of the outline is set via a normal CSS declaration in the media query).

Actual result
A red text is displayed in the green outline.
