Today I discovered a mis-implementation of the DOM API in Webkit, and I need some help updating MDN to reflect this... mutative node-moving builtins (IE,
insertBefore etc...) incorrectly return the
DocumentFragment when given one. The W3C specification states that these functions should move the child nodes of the
DocumentFragment, and that they should also return the inserted nodes. I looked at the C++ source code for that function, and it seems to be developer error.
