1536176 - Share LangGroupFontPrefs between documents.

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement, P3)

Description

[Emilio Cobos Álvarez [:emilio]]

My patch for bug 1535788 causes some pref-usage-at-startup tests to fail, given we query the default variable font and some prefs for every document now.

We should share these across documents.

All lang groups are static, no point in doing refcounting.

And also don't blow the preferences away unless they actually change. We were
blowing them away whenever the document language changed or what not, that's not
good.

Depends on D23954
