v4 textmacros extension crash

[pkra]

[Here's hoping I didn't (again) overlook an existing open issue.]

Using just https://cdn.jsdelivr.net/npm/mathjax@4.0.0-beta.3/tex-mml-chtml.js (or in my case, a basic nodejs setup), I get a crash for, e.g., \text{hello} (or \(\require{textmacros} \text{hello}\) on the client).

While the error is caught client-side as "Math Input error", the context menu lets me spy e.getProperty is not a function which seems to match nodejs where I get

TypeError: node.getProperty is not a function

Nope, this is a new one. I can reproduce, and will look into it.

Thanks, Davide.

Found it. It was a bad last-minute edit on my part. The PR listed above fixes it.
