Support customizable select elements

[zOadT]

Hey!

Customizable select elements will be supported in Chrome 135 without a feature flag (release is scheduled for Apr 1).

The HTML parser got changed to allow more elements as children of <select> elements. This library still checks the previous rules:

> isValidHTMLNesting("select", "button")
false
