Can an IOManager access metadata that is added to the output in the Op? When I try the below, I get an error saying that there is no key with "num_rows".

In the op:
```return Output(result, metadata={"num_rows": num_rows})```
in the IOManager:
```def handle_output(context, obj):
  num_rows = context.metadata["num_rows"]
  ....```

yea it’s a bug - <https://github.com/dagster-io/dagster/issues/12873>

As an alternative to this, could I add a second Output to the op and it would be handled by the same IO Manager? or is that not possible?

I suppose I could just make it a Tuple and access the metadata as a dictionary passed in that way
