Bug summary

UserWarning: Could not render math expression \sum_{\substack{1\leq i\leq 3\\ 1\leq j\leq 5}}

e.g. in #29801.

I suspect this may be a bug in pyparsing 3.2.2, which was released today. Ping @ptmcg

Code for reproduction

I've not yet created a minimal example from the docs, but can do so if additional insight is needed.

Actual outcome
