KaTeX Math Source should be ignored by ProseMirror inputRules

[benrbray]

Given a ProseMirror instance with both prosemirror-math and an input rule for automatically detecting *italic* text, type the following:

The two functions $f(n)=(5+n)*2$ and $g(n)=(n*2)+10$ are...

Since math source is currently represented as a text node, ProseMirror will scan the math source processing inputRules. In this example, it will recognize the substring *2$ and $g(n)=(n* as italic text and erase one of the math blocks.

Possible solutions:

• keep math source in an attr instead
• re-implement the inputRules to somehow ignore custom nodeViews
