Bug report

When a TreeView is bound to a new kendo.data.HierarchicalDataSource the binding of the widget breaks.

Reproduction of the problem

1. Run this Dojo
2. Notice that when the new DataSource is set the expand icon of the parent disappears.

In the wrappers the following error is thrown:
Uncaught TypeError: Cannot read properties of undefined (reading 'length')

Review the behavior in this Telerik Core REPL.

Expected/desired behavior

The TreeView should bind to the new data set successfully.

Environment
