Note to myself: improve the documentation to take care of the case exposed
in the screenshot. In case the processor does not accept incoming connection,
the documentation should not say "evaluated per flow file" even though the
scope is saying otherwise. That's because a property can be shared between two
processors with different annotations for incoming connections.---
