Feature Display Order not respected in AppStudio apps (e.g. Map Viewer 5.3)

Recently functionality was added to the Web Map to allow you to specify a Feature Display Order (https://doc.arcgis.com/en/arcgis-online/create-maps/set-feature-display-order.htm), which is great and works a treat. But the setting isn't respected in apps created in AppStudio using the exact same Web Map.

I have a Web Map with a single point dataset.  In the Web Map I've specified the Feature Display Order so that points with particular attribute values are always drawn on top.  In the screen grab below note that the green (library) features are drawn on top of the blue ones:

I've created a really simple app in AppStudio using the Map Viewer (5.3) template that displays just this Web Map.  But in the app, the Feature Display Order is not respected (note that the blue features are drawn on top of the green ones in the exact same area):

I can't find any way to make the app respect the Feature Display Order set in the Web Map. Does anyone know if this is possible?  @ZaraMatheson - your blog article (https://www.esri.com/arcgis-blog/products/arcgis-online/mapping/overlapping-features-feature-display...) doesn't mention any limitations with the setting

Hi Ian, Runtime / AppStudio does not yet support feature display order set in the web map, so this is expected for now. It will be supported at some point, but no definitive timeline yet.

Thanks for getting back to me @ZaraMatheson, I'll keep an eye out for it being supported in the future.
