Fail fast exception in DirectUI::DragDrop destructor (UWP app)

I have a UWP app in the Store.

I'm getting a few exceptions in the Partner Center for my app which are labelled as
```
fail_fast_fatal_app_exit_c0000409_windows.ui.xaml.dll!ctl::comptr_iinspectable_::internalrelease
```
with stack trace

From the stack trace, this is happening when an application view is closing. My app supports multiple windows, so I don't know if this when the app finally exits or just a window closing. In the former case, I was wondering if it might be related to COM shutting down before the `DirectUI::DragDrop` constructor being called? That's just a suggestion though.

Start with the reported stack trace at DirectUI::DragDrop::~DragDrop and follow its callers through DXamlCore::DeleteDragDrop, DXamlCore::Deinitialize, and FrameworkView::Uninitialize. Reproduce shutdown for a multi-window UWP app, comparing a single window closing with final application exit; done means the lifecycle condition causing the fail-fast exception is identified and addressed.
