1644285 - Wrong Arimo fonts selected on anandtech.com

Status: VERIFIED FIXED

(Core :: Layout: Text and Fonts, defect)

Description

[Johannes Pfrang [:johnp]]

With gfx.e10s.font-list.shared;true on latest Nightly and google-croscore-arimo-fonts installed on Fedora 32 the Arimo font on anandtech.com selects the bold italic variant in the main text (font-weight: 400) and the regular one in the "Pipeline Stories" header (font-weight: 700). Fonts are chosen correctly with the shared font list disabled. This also happens with a clean profile (only gfx.e10s.font-list.shared;true) as early as Firefox version 68.

That's....weird. I can reproduce also on Ubuntu with the fonts-croscore package installed. Will look into it; thanks for reporting.

OK, I think I see what the problem is here. When collecting the font names for src:local() lookups we record the family and face index within the family of each available font; but then when storing the faces into the font list, we potentially re-sort the faces (if it is a "simple" family with no more than the standard 4 styles), and that invalidates the face indexes that we stored in the src:local table.
