Disposing a shared CanvasDevice (despite documentation warning against it) causes a crash when an app's resize events fire.
Expected behavior
Per docs, I expect subsequent GetSharedDevice() calls to safely recreate and return a new device.
If the Canvas itself is a component using the shared device, then the docs are wrong because there would never be a scenario where "no other components are using it".
Actual behavior
App crashes.
