See https://w3c.github.io/mathml-core/#the-a-element
We do render that element as mrow after bug 1958853.
This bug is about deprecating href on other elements.

In MathML Core, links are only supported on <a> elements.

- XLink href support has been removed:
https://github.com/w3c/mathml/issues/127 - In the present bug 2026848, href support on all but <a> elements is
being disabled via the
mathml.href_link_on_non_anchor_element.disabledruntime preference.
See https://github.com/w3c/mathml-core/issues/142 - Also make
ContextMenuChild.sys.mjsaware of MathML links, so that
they appear in the context menu (bug 958957). MathMLElementis now a thing so use it to handle the MathML case.
https://github.com/w3c/mathml-core/issues/129- Also rely on
SVGAElement.

We need to update the documentation here:
- MathML has a new
<a>element which behaves like an<mrow>https://w3c.github.io/mathml-core/#the-a-element (it's render as an mrow since bug 1958853) - The href attribute is deprecated on all MathML elements but
<a>.

I noticed that <a href> in MathML comes without underline style by default, which is an a11y concern. Are there any discussions/work happening around that?

I know there were old bugs in browsers when underline was used, as that changes the layout. I guess this should be discussed on the MathML Core repo.

I think it's fair to set this to DDC; see https://github.com/mdn/content/issues/43859 for links to BCD and docs work.
