I am using ubuntu 24 with the latest chrome version with the font art DejaVu Math Tex Gyre. (But with other fonts the result is the same.)
The Latex-Code <math>{\bf Spec}, \bf A, \bf B, \bf C, \bf D, \bf E, \bf F, \bf G</math> is not rendered correctly using Native MathMl. The letters are not displayed in bold.
Hi,
the screenshot is taken from https://de.wikipedia.beta.wmflabs.org/wiki/Intbar#Bf-Stil.
Thank you. Local testing reveals that the problem seems to be that chrome ignores mathvariant=bold.
See https://developer.mozilla.org/en-US/docs/Web/MathML/Element/mi#bold explains that the mathvariant solution is actually deprecated. We can use the same procedure as we used for fraktur etc.
Change #1110455 had a related patch set uploaded (by Physikerwelt; author: Physikerwelt):
[mediawiki/extensions/Math@master] Add fallback unicode mappings for bold font
I've added this as case 13 at https://www.mediawiki.org/wiki/Extension:Math/Native_MathML/Reported_Cases.
It seems to render fine in Firefox already without this patch, but indeed not in Chrome:
Firefox 134:
Chrome 131:
With the patch applied locally, it renders bold in both (top Chrome, bottom Firefox):
