📄 Description

There is a bug in the compiler that we trip over when we handle the
exception generated by Package::Current inside a coroutine. It appears
to destruct an invalid instance of winrt::factory_guard_count.

Learned from the compiler folks: "coroutine frame pointer wasn't being
stored ... properly".

Fixes #9821
