[issue21379] StopIteration is silenced when raised by generator within context manager

[Nick Coghlan]

Nick Coghlan added the comment:

This is expected behaviour - "raise StopIteration" in a generator is equivalent to "return", except it can occur inside a called function.

The bug here is in the given context manager definition - it should be taking appropriate action if the "next" call failing is supposed to be treated as an error rather than termination of the generator.
