\newcommand rendered in red even though it works

[danjenson]

Describe the bug

\newcommand isn't recognized and yields red text, even though it renders where used with the globalGroup turned on.

To Reproduce Steps to reproduce the behavior:

$$
\newcommand{\chk}{\checkmark}
$$
$$
\chk
$$

Works, but the first block is rendered in red.
