Description
Describe the bug
Hello,
as an example, I am defining a ui:ListView:
<ui:ListView Grid.Row="1" Grid.ColumnSpan="1">
<ui:ListView.View>
<ui:GridView>
<GridViewColumn Header="Test" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</ui:GridView>
</ui:ListView.View>
<ListViewItem>
<ListViewItem.Content>
<x:Array Type="{x:Type sys:String}">
<sys:String>Test</sys:String>
</x:Array>
</ListViewItem.Content>
</ListViewItem>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
</Style>
</ListView.ItemContainerStyle>
</ui:ListView>`
As soon as
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
</Style>
</ListView.ItemContainerStyle>`
is applied, every Style setting from WPF-UI is gone. Also there is no possibility for BasedOn.
Am I missing something, or is that a Bug?
Thanks!

Research direction
Start with the XAML reproduction showing an empty ListView.ItemContainerStyle on WPF-UI's ListView. Trace how that style is applied and compare the resulting control styling with the default case. Done means the WPF-UI style settings remain when a custom ItemContainerStyle is supplied, while the issue's expected behavior is covered by a regression test.
