Per browsers and reality, "data:text/html#foo" is alerted. See https://bugzilla.mozilla.org/show_bug.cgi?id=308590 for why the web depends on this behavior. See https://bugzilla.mozilla.org/show_bug.cgi?id=1157953 for why we probably want a similar behavior for "about:blank" as base URL. There may be other non-relative schemes or particular URIs from those schemes (maybe even all?) that want this behavior. 121009 1 annevk 2015-06-15 17:25:10 +0000 https://github.com/w3c/web-platform-tests/pull/1902 (Gecko fails these for unrelated reasons). https://github.com/whatwg/url/commit/7468c397f600b72f650f52fc02466f051bf96ad3
