FirstAsync does not throw on ReplaySubject

[WolfBublitz]

Example

using R3;

ReplaySubject<int> subject = new();

subject.OnErrorResume(new Exception("test"));

int value = await subject.FirstAsync(); // except to throw

Expected Behaviour

The awaited FirstAsync call should throw the exception.

Actual Behaviour

The awaited FirstAsync call never returns.
