Description
This is needed when MathML is rendered without a font with an OpenType table.
Gecko, WebKit, OpenType MATH and TeX have some values. We need to check whether they are consistent and easily usable: https://mathml-refresh.github.io/math-constants.html
I think this might be difficult to test as some parameters interact between each other in the layout but we don't have much freedom to set independent values without a MATH font (most of the suggested fallbacks are based on font em or x-height IIRC).

Research direction
Start with the linked math-constants.html comparison and review the Gecko, WebKit, OpenType MATH, and TeX values it discusses. Determine whether the values are consistent and suitable as fallbacks when no OpenType MATH font is available, then define the required behavior and how interacting parameters could be tested.
