Note: this is a patch port of the changes from #55631.
Fixes that we didn't have the MathML elements in the schema. Note that we can't discover which tag names are available by looking at globally-available classes, because all MathML elements are MathMLElement rather than something like SVGCircleElement. As such, I ended up having to hardcode the currently-available tags.
