math syntax vs GitHub

[ejhyer]

GitHub passes blocks marked with ```math to the math rendering engine:

$$E = mc^2$$

Slidev expects math blocks to be marked with $$. GitHub recognizes that syntax, too, but I have a lot of pre-existing *.md that use the other convention.

Is there a method to get slidev to parse ```math blocks? I have fooled around with @slidev/client/setup/preparser.ts but I cannot get past
