/**
 * Matches a compound selector such as `slot[name="footer"]` or `div.row#first`.
 *
 * Every qualifier must match. Supporting only one at a time meant a selector like
 * `slot[name="footer"]` fell through to the tag comparison and matched nothing, which broke
 * server rendering for any component that located a node that way — silently, because a
 * `querySelector` returning null there is usually asserted away with `!`.
 *
 * Anything the tokenizer cannot consume in full — a descendant combinator, `>`, a
 * pseudo-class — returns false rather than matching on the part it understood. A selector
 * this engine does not implement should find nothing, not something arbitrary.
 *
 * @param node The node to test.
 * @param selector The selector to match.
 * @returns Whether the node matches every part of the selector.
