#406 MathML uses invalid attribute "fontweight" instead of "style"

[ManDay]

There is no attribute fontweight on <mstyle> (3.3.4 Style Change), the translation of \mathbf therefore does not work in W3C conformant browsers. The correct attribute is style="font-weight:bold".

Needed change, for what it's worth.

Thank you for the report and patch.
Unfortunately, with the output of

.. math::

       a = \mathbf{c}^2 + \mathrm{d}x

my firefox (78.4.0esr) ignores the style="font-weight:bold" argument
(just as it ignored the fontweight).
OTOH, WebKit and Chromium show a bold "c" but the 2 is no superscript and all variables are upright :(

[Günter Milde]

After a new look, I would suggest to use the "mathvariant" attribute on <mi> instead of a style wrapper for \mathbf (which in LaTeX is used to convey semantics of a variable, not just style).

Fixed in r8675 with a modified version of the provided patch (mathvariant="bold" instead of the "style" attribute).
Thank you for the report and patch.
