Issue with Tree Widget UI rendering when used with Networks( _BMCollectionViewInfoTableIndex)

Hi All,

           We are facing issue with Tree Widget UI rendering when used with networks.

Explanation: We are trying to display below sample network  structure in tree widget.

ABC

            XYZ

                    Animal

                               Cat

                   Fruit

                              Apple

                             Watermelon

                  Location

                               India

                               US

Whenever we delete Cat from Animal,if we click on Animal again,then click on Fruit, it will not show Apple and Watermelon,it goes same with any same level parent element.

We inspected in browser console.We got the below error.

We tried in both Microsoft Edge(IE) and Chrome.
