Dark mode behaviour

[sorilee]

Thank you for this amazing extension which my blog with posts on category theory is heavily dependent on.

When I tried out dark mode on my blog, all MathJax renderings were displayed accordingly in white, except the diagrams rendered by XyJax-v3. Below is a screenshot of this.

Could the diagrams be made to be displayed in the same style as other MathJax renderings even in dark mode? (If you could hint which part of the code should be adjusted, I could also attempt to make a fix myself if it is within my reach.)
