Added fix for display hook call output format #11101
Hit an issue were under complex conditions, that are hard to express in a simple notebook, the displayhook was building output array elements in the old tuple format instead of the kwarg format. This causes (ignore py2 package path in the stack trace example):
Tracing down the fix was to adjust the callable which was not updated. Tracing the capture code throughout the project was a real headache as the global state is touched a lot along the way, so I made a spec just to prove that the output format conforms rather than express where that hook callable is made consequentially.
