KaTeX/LaTeX math with diagrams doesn't display

[mmxhello]

Hello,
The problem is, when I use Latex/Katex syntax to add text on my diagram in the draw.io editor and save the diagram, it won't display in the diagram preview in the article, but if I open the editor again, it's OK there.

KaTeX and Mathjax are enabled in settings, also Diagrams Post-Processor is enabled:

I've already tried different combinations of these settings and some other text parameters in the diagrams editor.

The problem looks like:

As you can see, all tex-styled text disappears.

Also I've tried different options of math syntax in the diagrams editor as mentioned in its documentation
, but they all also don't help the result - the text doesn't appear.

If I export diagram in .jpg/.png/.svg, it looks as it should be and all the text displays.
