Windows Automation tree breaking change

### Description

Dotnet 8 renders the controls in the Windows automation tree differently compared to earlier dotnet versions.
Buttons in an itemscontrol can't be found anymore, breaking the existing automation.

Using the "Accessabilitiy Insights for Windows" shows a different graph compared to dotnet 6/7 (see below)

### Reproduction Steps

[WpfApp3.zip](https://github.com/dotnet/wpf/files/13917169/WpfApp3.zip)

### Expected behavior

With `net7.0-windows` , the automation tree looks like
pane "Desktop 1"
window "MainWindow"
title bar ''
button "TopButton"
button "ItemButton1"

### Actual behavior

With `net8.0-windows`, the automation tree looks like

pane "Desktop 1"
window "MainWindow"
title bar ''
button "TopButton"
list view #note that here was the "ItemButton1" - now it is not present anymore!
