=== Feature requested:
We want MediaWiki to support more LaTeX AMS environments in its `<math>` environment.
This is part of a wish in the 2022 wishlist: https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2022/Editing/Missing_LaTeX_capabilities_for_math_rendering
=== Functionality/software changes
These environments are already supported by MathJax. So, all we have to do is change [[https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/services/texvcjs/|texvcjs]] to allow these commands to be passed to MathJax in the backend.
[] Extra environments are supported by [[https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/services/texvcjs/|texvcjs]]
AMS environments which we probably could support:
* [] gather
* [] gathered
* [] multline
* [] CD
* [] split
* [] subarray
