Invisible in web assembly

[Moisha]

TreeDataGrid works well in desktop version but invisible in browser. And make other controls invisible.
Tried on Windows and Ubuntu, result is the same.
For example this view

<TreeDataGrid Name="treeGrid" Source="{Binding Source}" HorizontalAlignment="Center" VerticalAlignment="Center" Width = "300" Height="300" />

and this view

<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<TreeView Name="tree" ItemsSource="{Binding Items}" HorizontalAlignment="Left" VerticalAlignment="Stretch" Width = "300" />
<TreeDataGrid Name="treeGrid" Source="{Binding Source}" HorizontalAlignment="Left" VerticalAlignment="Stretch" Width = "300" />
</StackPanel>

are totally invisible in browser. Changing places TreeView and TreeDataGrid has no effect.

Removing TreeDataGrid from second view immediately reveals TreeView.

fwiw, I've had it working in WASM before with Avalonia 11.0, and just tried it with the latest Avalonia 11.1 nightly and it seems ok (only a simple setup with a HierarchicalTreeDataGridSource but still)
