I think this could affect B2G if we ever created a GL context in the main process.

[Triage Comment]
Approving for mozilla-beta 19 and mozilla-b2g18. We wouldn't typically take a change of this nature without significant user impact, but with a week until release and only 2 days of bake time for the regressing bug, it's worth it to take a trivial fix.
