Hello. Does anyone know why, when using .asSingle() on a Deferred<T> from the kotlinx-coroutines-rx2 library, why the coroutineContext I pass into .asSingle() can't contain a Job?

I see it throws an IllegalArgumentException but am unclear why.

Because the lifecycle is managed by RX Disposable and not by a context’s Job:

Ah okay, that makes sense. Thanks!
