Browser preview does not use MathJax preamble in card template

[JeppeKlitgaard]

I have a MathJax preamble defined in my front and back card templates. This is respected in some places (views/previews), but not in others (editors).

I would have expected and liked for the WYSIWYG editor to also include these, though I understand that the MathJax instance used here does not have access to the context of the card.

Would there be a good workaround available?

I don't think there's a simple workaround. Maybe this should be customizable from the Note Types screen like it's done for LaTeX.

I think that would be a great solution and definitely something I would love to see. This would serve much the same use-case as the existing Latex preamble

I have been working a bit on this and discovered a few dumps in the road that might require the input of someone more knowledgeable and opinionated than myself.

Currently the MathJax object is stored as a global singleton, which is nice for memory purposes, but slightly problematic in that it can be mutated using macros like \newcommand{}, which could lead to clashes between notes/notetypes. See: mathjax/MathJax#3275

Even as is, the state will 'bleed' from one note to the other in the browser and during a study session.
