The plugin does not work properly in the latest version of Firefox 88.0.

Hello,
Thanks for this plugin. It is very helpful in writing equations.
Everything works fine in Chrome but unfortunately it does not work properly in the latest version of Firefox 88.0. The math symbols preview is not displayed in the dialog box below the LaTeX input window.
It would be great to be able to edit the math symbols that inherit the color styles and font sizes set in TinyMCE. Also please, add the ability to add an icon from Font Awesome.
Please, add this features.
Best Regards
