Description
Fairly minimal example would be $$\genfrac{}{}{-1pt}{4}{a}{b}$$.
On both mathjax.org#demo and our almost-v4-alpha build, this gives an error of "Bad math style for \genfrac".
However, "real" TeX seems ok with this.

Research direction
Start by reproducing $$\genfrac{}{}{-1pt}{4}{a}{b}$$ in the mathjax.org demo and the almost-v4-alpha build, then trace how \genfrac validates its math style. Done means this TeX-valid input renders without the “Bad math style for \genfrac” error and the behavior is covered by an appropriate regression check.
