Node.removeChild removes parent from document id's

[ejones]

The following for-loop in the definition of Node.removeChild seems to be using this, i.e., the parent node, in places where the child was intended:

    for (var i=0;i < this._children.length;i++) {
      if (this._children[i] === oldChild) {
        found=true;
        this._children.remove(i,i);
        oldChild._parentNode = null;

        if (this.id) {
          if (this._ownerDocument._ids) {
            this._ownerDocument._ids[this.id] = null;
            delete this._ownerDocument._ids[this.id];
          }
        }

        if (this.nodeType === this.DOCUMENT_NODE) {
          if (this._documentElement === oldChild) {
            this._documentElement = null;// force a recalculation
          }
        }

        return oldChild;
      }
    }

In particular, it removes the parent from the document's id list, effectively hiding it from getElementById
