Crash during selection change

[kant2002]

Admittely I have this bug in NativeAOT context, but I cannot understand why this cannot happens in regular app.

I open Structured Log Viewer on WPF binlog and start quickly double-click and change selection in the tree view.

Simplified version of what's going on. TreeView (master) + ListView (details).
When something selected in the TreeView, Items in the ListView updated using

breadCrumb.Items = chain; // Crash here
breadCrumb.SelectedIndex = -1;

I suspect that if I click too quickly issue happens. Maybe I miss some standard way how I check Avalonia ListBox that right now update happens, so I postpone setting items.

Stack Trace

It seems to be issue with

[workgroupengineering]

Probaly the problem is here:

Avalonia/src/Avalonia.Controls/Selection/SelectionModel.cs

Lines 301 to 304 in ecb0de2

	foreach (T i in _initSelectedItems)
	{
	Select(ItemsView.IndexOf(i));
	}

One of possible solution is call ToList() before foreach

                        var copy = _initSelectedItems.ToList();
                        foreach (T i in copy)
                        {
                            Select(ItemsView.IndexOf(i));
                        }
