### Beta/Release Uplift Approval Request
* **Feature/Bug causing the regression**: Google using a new font for Pixel phones
* **User impact if declined**: On phones shipping Google Sans instead of Roboto, pages specifying sans-serif fonts won't be rendered properly because we might not have any other sans-serif font to fall back to.
* **Is this code covered by automated tests?**: No
* **Has the fix been verified in Nightly?**: No
* **Needs manual test from QE?**: Yes
* **If yes, steps to reproduce**: 
* **List of other uplifts needed**: none
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: Simply extending the font list preference so we accept Google Sans as an alternative sans-serif font if Roboto isn't available.
* **String changes made/needed**: none
