Description Chris Dumez 2022-01-14 13:05:35 PST 
Clarify / Optimize <select> logic given that deeply nested <option> or <optgroup> are not supported, as per specification.

An <option> is only associated with a <select> element if it is either a child of the <select> or a child of an <optgroup> that is itself a child of the <select>:
- https://html.spec.whatwg.org/multipage/form-elements.html#concept-select-option-list

As a result, an <optgroup> is only associated with a <select> element if it is a child of that <select>.
