There are large number of items for the TreeList (for example 3000) and you have all them initially collapsed.
For example you could modify the IsExpandedBinding demo to have 3000 items.
Then scroll down so the row with Drinks and Count = 2194 is at the top of the control and expand it.
The result is that both that row and the row with Drinks and Count = 2199 expand.

When expanding or collapsing an item fast, mouse over effect or expand/collapse appears on a different row. The row needs to be the recycled one. This means that you need to have more items in the viewport and scroll to the bottom for example.

The JAWS screen reader cannot read the RadTreeListView and also its rows and cells.

This reproduces after the 2019.3.917 release.

To work this around create a custom RadTreeListViewAutomationPeer:

public class CustomTreeListView : RadTreeListView
{
	protected override AutomationPeer OnCreateAutomationPeer()
	{
		return new CustomTreeListViewAutomationPeer(this);
	}
}

public class CustomTreeListViewAutomationPeer : RadTreeListViewAutomationPeer
{
	public CustomTreeListViewAutomationPeer(RadTreeListView owner) 
		: base(owner)
	{
		var methodInfo = typeof(RadTreeListViewAutomationPeer).GetMethod("GetItemPeers", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
		methodInfo.Invoke(this, null);
	}

	protected override List<AutomationPeer> GetChildrenCore()
	{
		var frameworkPeer = new FrameworkElementAutomationPeer((FrameworkElement)this.Owner);
		return frameworkPeer.GetChildren();
	}
}
