document.importNode(node, deep): deep's default value should be false: https://dom.spec.whatwg.org/#interface-document https://dom.spec.whatwg.org/#dom-document-importnode Firefox and Chrome follow the specification. However, WebKit uses "true" for deep's default value. Note that WebKit use to have "false" as default value but this was changed in Bug 71190 because the DOM spec said to use "false" at the time :(
