The async, off-stack part of DebuggerStackTrace::CollectAwaiterReturn's stack unwinding incorrectly looked on the stack instead of following the Closure's awaiter chain. This caused the async stack traces to be truncated and missing any async frames, in turn causing ShouldPauseOnException to incorrectly conclude no handler frame existing. This would affect any case where the exception handling was located around any except for the inner most awaiter.
