FWIW, I recently stumbled upon this bug and I think nowadays we do what comment #1 (from 2006!) says Firefox used to do back then. The thing that makes this fail is DOMSelection.cpp:getRangeAt, which has a chunk like:

    if (Node* shadowAncestor = selectionShadowAncestor(m_frame)) {
        ContainerNode* container = shadowAncestor->parentNodeGuaranteedHostFree();
        int offset = shadowAncestor->nodeIndex();
        return Range::create(shadowAncestor->document(), container, offset, container, offset);

triggered inside text areas (and that makes us return a 0-0 bogus range). If I just *remove* that code, my simple tests seem to work OK, but I'm sure that breaks something else somewhere.
