Sorry for the delay in getting back to you. I ended up being rather busy around
the middle of last year. I’ve just started another sprint on the LaTeX preview
rewrite, and have made a few changes to how face guessing heuristics.

If you might be willing to try the new code and see if the issue noticed still
appears, that would be brilliant!

All the best,
Timothy
