Undo should not affect elements that are not editable

If an element changes from editable to non-editable, all undo commands that apply to it and its descendant should be ignored.
Same goes for redo.

Are there cases where the parent isn't editable, and its not attached, where we would want to allow the AppendNodeCommand?

I don't think so. Look at the ASSERT in the constructor.
    ASSERT(m_parent->isContentEditable() || !m_parent->attached());
