Comment on attachment 403906 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=403906&action=review I think you should be able to write a pretty simple ref test for this. <canvas> <div></div> draw into canvas element canvas.remove(); divElement.appendChild(canvas); > Source/WebCore/html/HTMLCanvasElement.cpp:1014 > + if (insertionType.connectedToDocument) > + addObserver(parentOfInsertedTree.document()); Can it be our document() at this point? I expect this is called after the insertion has happened.

Just to avoid Node::?

Wrote a ref test, but could not get it to play nice with WebKitTestRunner. Upon advice, skipping the test for now.
