Fred, who works at Igalia and implemented MathML in WebKit, pointed out we could try to simplify some stuff.

Some links:

Also the appendix on

For stuff that we could / should consider removing.

Some of it is really invasive (the script size multipliers come to mind), so it'd really be nice to simplify some of this stuff.
Component: Audio/Video: GMP → MathML

As announced on, a MathML Refresh CG has been launched early this year and some simplification is being discussed and formally approved:

Let's use this as a meta bug similar to WebKit's one ( )

This is bug 1587577

This is bug 1548524, bug 1573438 and bug 1575870 basically.

Most mstyle attributes have been removed for a long time. The remaining ones are bug 1548471. Also we might want to map mathvariant/displaystyle/scriptlevel to the CSS properties described in the spec, instead of internal ones.

This is bug 1548529.

This is bug 1548522.
