This change adds checking for the following spec requirements: - https://html.spec.whatwg.org/#number-state-(type=number):value-sanitization-algorithm - https://html.spec.whatwg.org/#range-state-(type=range):value-sanitization-algorithm That is, it adds checking that HTMLInputElement.value is what the spec defines as a “valid floating-point number” when the “type” attribute for the HTMLInputElement is either “number” or “range”. This change causes Ladybird to pass all the failing tests at https://wpt.fyi/results/html/semantics/forms/the-input-element/number.html?run_id=5080423051034624 and to match the relevant behavior in Webkit, Blink, and Gecko. Otherwise, without this change, Ladybird fails those tests, and the relevant Ladybird behavior isn’t interoperable with other engines.
