I am using Kendo TreeList (ver 3.0.2) in my Angular 11 project. The TreeList is loaded with more than 25000 data at the parent level and child data is loaded with backend api call. Virtual scrolling is enabled for the TreeList and navigable option is set to true.

I have a requirement that when user performs a search operation, the application should fetch the search result and then it should expand the respective parent nodes and focus on the search result. The user shall be able to navigate through the search result one by one.

I am experiencing an issue that the Kendo TreeList is showing blank area on some randomly expanded and focused row. When I manually scroll on the view, the data get restored. Also, when I navigate to the next record and again come back to the previous record that time the view is rendered properly.

Please help.
