Steps to reproduce:
- Site with MathJax and TeX filters enabled. MathJax before TeX.
- Chemistry notation enabled in MathJax:
- filter_mathjaxloader | mathjaxconfig:
- In Moodle-course create a page and add mhchem-expressions.
We have found most mhchem-expressions rendering correctly.
The following expressions are broken though:
Rendering problems seem to occur only in \ce -expressions starting with "<".
We have found that this is a regression caused by MDL-69911.
With TeX-filter disabled or the parameter cleaning introduced by MDL-69911 commented out, the mhchem expressions are rendered correctly.
