Check if updating to the latest Preact version resolves the issue

Describe the bug
Preact doesn't correctly namespace MathML elements.

To Reproduce

Steps to reproduce the behavior:

Go to https://preactjs.com/repl?code=aW1wb3J0IHugcmVuZGVyIH0gZnJvbSAncHJlYWN0JzsKaW1wb3J0IHsgdXNlU3RhdGUgfSBmcm9tICdwcmVhY3QvaG9va3MnOwoKZnVuY3Rpb24gQ291bnRlcigpIHsKCXJldHVybiAoCgkJPD4KCTxtYXRoPjxtcm93PjEyMzwvbXJvdz48L21hdGg%2BCgk8c3ZnPjx0ZXh0PjEyMzwvdGV4dD48L3N2Zz4KCQk8Lz4KCSk7Cn0KCnJlbmRlcig8Q291bnRlciAvPiwgZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoJ2FwcCcpKTsK
In dev tools select the <math> element, then run $0.namespaceURI and you will see http://www.w3.org/1999/xhtml
If you then select the <svg> element, and repeat, you will correctly see http://www.w3.org/2000/svg

Expected behavior

I would expect Preact to handle MathML element namespacing correctly.

See https://w3c.github.io/mathml-core/ for the latest MathML spec.
