Does this also happen on a new template app? If so, then this is a bug in the windows api for unpackaged and needs to be opened on github.com/microsoft/WindowsAppSDK

This issue may be a bug: microsoft/WindowsAppSDK#2995

Waiting on a reply there to see if we should work around this or if this is different behaviour.
