Note: Since we call |DragCaretController::setCaretPosition()| with dirty layout
tree, |createVisiblePosition()| hits |DCHECK()|, this rewrite is safe.

     Document* document = nullptr;
     if (Node* node = m_position.deepEquivalent().anchorNode()) {
         m_caretBase->invalidateCaretRect(node);
