[Accessibility] In WPF Narrator is not reading the items of an Editable ComboBox

[adesypri]

Description

.NET Core Version: net8
Is this bug related specifically to tooling in Visual Studio (e.g. XAML Designer, Code editing, etc...)? No

This issue has been opened again #7005, however we noticed that the app does not send the events that the Narrator expects.

The attached video comes from our application, but we can also reproduce in the attached sample app.

This only reproduces when the ComboBox's IsEditable is True, and we have no customizations in the area.
