build error: TypeError: _ctx.a is not a function.

Reproduction

You can paste the follow txt in the markdown:

$S_n = \frac{{a(1 - r^n)}}{{1 - r}}$

and you will recevied a build error.

But, other Math Equations can normally build, like:

$S_N$

Expected behavior

Normal output page, even if it does not render mathematical formulas.
