Comment:

 If wrapping the `math` element with `p` tags can break it, it would make
 the most sense to add it to the list of excluded elements. Because it's a
 limited use element that's only viable in specialist use cases, I think
 the risk of breaking people's sites because they're expecting the tag to
 be wrapped in `p` is quite low.

 MathML, while still having poor native support, is the only practical way
 to communicate mathematics accessibly, so breaking that is a real problem.

 I think that the principle of `wpautop` is to attempt to wrap text that is
 either unmarked or marked only with inline elements; the exclusion list is
 intended to prevent breaking existing markup. Since running `wpautop` on
 `math` elements has a strong potential to break markup, I think it should
 be considered.
