问题 Does the FlipView control (I'm programming Universal Windows) support binding to a random access (virtualized) data source? The Microsoft docs ListView and GridView data virtualization suggest that it works for grid and list view but say nothing about FlipView.

I'm aware that I can use the ms-appx-web protocol to load such a file from my app bundle, but this is no option because the data to show are downloaded after install of the app. I also can't just use webView.navigateToString because this won't include the referenced libraries in the html file.
