Putting ComboBox into BreadcrumbBar crashes the app

[xperiandri]

Describe the bug

      <BreadcrumbBar ItemsSource="{x:Bind ViewModel.Path, Mode=OneWay}">
        <BreadcrumbBar.Template>
          <DataTemplate x:DataType="slf:FloorItemViewModel">
            <BreadcrumbBarItem Content="{Binding}">
              <BreadcrumbBarItem.ContentTemplate>
                <DataTemplate x:DataType="slf:FloorItemViewModel">
                  <ComboBox />

Putting a ComboBox in any form crashes the app.
But if you replace UI with a ComboBox later it works

2. Run

Workaround is

<DataTemplate x:DataType="slf:FloorItemViewModel">

    <i:Interaction.Behaviors>
      <ic:EventTriggerBehavior EventName="Loaded">
        <ic:ChangePropertyAction TargetObject="{Binding ElementName=FloorsSelector}" PropertyName="Visibility" Value="Visible"/>
      </ic:EventTriggerBehavior>
    </i:Interaction.Behaviors>
    <ComboBox x:Name="FloorsSelector" x:DeferLoadStrategy="Lazy"
            ItemsSource="{Binding Items}"
            IsTextSearchEnabled="True"
            PlaceholderText="Select floor"
            SelectedValuePath="Name"
            SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
      <ComboBox.ItemTemplate>
        <DataTemplate x:DataType="domain:BuildingFloor">
          <TextBlock Text="{x:Bind Name}" />
        </DataTemplate>
      </ComboBox.ItemTemplate>
    </ComboBox>
  </Grid>
</DataTemplate>

x:DeferLoadStrategy="Lazy" + trigger
