The two attributes are fine in “living” HTML, as per https://html.spec.whatwg.org/multipage/iframe-embed-object.html#the-iframe-element. However, the page suggests it’s using HTML 4.01, which doesn’t recognize these attributes: https://www.w3.org/TR/html401/present/frames.html#h-16.5. It may be a sound choice in general to switch to the HTML doctype (`<!DOCTYPE html>`), however that may require more adjustments than just these two.
