--- Comment #14 from Ryosuke Niwa <rniwa at webkit.org> ---
Right. Consider an operation to remove a node for example. To undo this removal we need to inset back the original node that got removed since other steps that ran before or after this undo step may reference the removed node as an insertion point, etc... our undo / redo stack currently relies on the exact same DOM structure to be restored at each step.
