Bug 1535788 - Make the Document own the StyleSet. r=heycam This is the last step to be able to call matchMedia on display: none iframes. This is green, except for some startup preference query tests that I'm going to address in a blocking bug (making LangGroupFontPrefs global, basically). The setup is similar to the ShadowRoot one, except we don't eagerly keep the StyleSet around up-to-date, we only fill it if it ever had a pres context. Differential Revision:
