Describe the bug

After using math font package in tex_template of ManinGL，such as “\usepackage{fourier}”, once I use the latex command that involves changing words size， the TexText will be displayed incorrectly， such as “$x^{y}$ ”, “ $x_{y}$”, ”{\small $x$}+$y$".

I inspect the (.svg) file it outputs. the result is correct. So I think it is a displayed bug Code:

Wrong display or Error traceback:
