GHSA-9JH8-V38H-CVHR ammonia: mXSS via MathML `annotation-xml` encoding strip

If a certain set of MathML tags are enabled, an attacker can inject arbitrary JavaScript code into the user's browser. The annotation-xml tag has slightly different behavior than the other "integration point" tags in MathML and SVG, but ammonia didn't handle it, so it didn't correctly strip the...
