(This is tested using the bots on wpt.fyi; I do not have a Mac available in these working from home times.) URL: http://wpt.live/dom/nodes/DocumentFragment-getElementById.html Per spec, documentFragment.getElementById("") should return null, even if there is a <div id=""></div> inside the DocumentFragment. Safari passes the same test for document.getElementById(""): http://wpt.live/dom/nodes/Document-getElementById.html . Other browsers: Chrome fails, Firefox passes Spec reference: https://dom.spec.whatwg.org/#concept-id ("value is null or the empty string").
