TOC Stuck at the bottom of the list when a layer activated from Search Bar.

Steps to re-create the issue.
1- Load the map (https://opengis.simcoe.ca).
2- Search for School.
3- Click to the School (Popular Layers) – or you can search and click any other layer in a list other than All Layers.
4- Back to Search bar and search School again.
5- This time pick the School (All Layers).
6- Issue: -- TOC Scrolls to the bottom of the All Layers list and for 8-9 second doesn’t let you scroll up using scroll bar or Mouse.
