Summary
Treat
<math>elements as atomic entities during DOM-to-Content-Model conversion so their nested MathML remains intact. Extend HTML sanitization to allow MathML elements and preserve their MathML namespace instead of replacing them with HTML fallback spans.How to test
yarn test:fast --testPathPattern="(elementProcessorTest|sanitizeElementTest)".<math><mrow><mi>x</mi><mo>+</mo><mn>1</mn></mrow></math>to a Content Model and confirm the formula is represented by one entity whose wrapper retains the nested MathML.http://www.w3.org/1998/Math/MathMLnamespace are preserved.
