I think it is more serious than whether or not mathjax is used.

Why place "tabular" inside math, especially inline math?

This cannot sensibly become HTML because one cannot put a block element
-- <table> -- inside an inline element -- <math display="inline">.

Making use of a suitable LaTeX profile should trap problems of this

(I find that simply removing the '$' markup in the first
cell of the outer tabular surrounding the inner tabular will
fix it.)
