Text variable does not lose reference to a "Format Text" node after the node is deleted

After deleting a format text node, if a text variable was plugged into it the variable's pin will stay highlighted as though it were still connected. If this is then hooked up to the return pin of a bound text function it will throw an error (shown in attached image).
