Math enviroment not supported in .drawio.svg files

[YiDingg]

When inserting .drawio.svg file into .tex file, math formulars can not be rendered and displayed properly (I am sure that "mathematical typesetting" is openned).

For example, here are my .drawio.svg file and the .tex code to insert svg graphics:

% code to insert svg in .tex file
\begin{figure}[H]\centering
\includesvg[width=0.7\textwidth]{assets/受控电源电路符号.drawio.svg}
\caption{\textbf{受控电源电路符号}}\label{受控电源电路符号}
\end{figure}

The svg file is displayed as below:

And I am sure "mathematical typesetting mode" is openned.

It would be appreciated if this problem can be fixed.

I also tried the .drawio.svg file whose name was completely in English, but it doesn't work.
