This is just a minor test flakiness issue with the isolation test.
Apparently, we need to force a deterministic report position by adding
a no-op step to the splitter's session.

Attached v2 has a more stable version of the isolation test (no other
changes compared to V1). Does this version work for you?

The isolation test is just for illustrative purposes. I don't think
that it's committable.
