Message:

HTML API: Add support for SVG and MathML (Foreign content)

As part of work to add more spec support to the HTML API, this patch adds
support for SVG and MathML elements, or more generally, "foreign content."

The rules in foreign content are a mix of XML and HTML parsing rules and
introduce additional complexity into the processor, but is important in
order to avoid getting lost when inside these elements.

Developed in ​https://github.com/wordpress/wordpress-develop/pull/6006
Discussed in https://core.trac.wordpress.org/ticket/61576

Props: dmsnell, jonsurrell, westonruter.
See #61576.
