When setting `DEBUG_PROPAGATE_EXCEPTIONS = True` the exception gets re-
raised in the view, but still gets handled/swallowed by `runserver` then.

Therefore `python -m pdb ./manage.py runserver --nothreading --noreload`
does not allow for post-mortem debugging then.

This could be fixed by implementing `handle_error` on the `WSGIServer` and
`ServerHandler` used by the runserver command.

Comment:

Hey Daniel. Interesting idea. I'm not sure of the benefit… maybe it's
worth it, but I've always found setting a breakpoint in an erroring view
to be sufficient. 🤔

Can I ask you to follow-up on the DevelopersMailingList to see what others
think, and to canvas suggestions on the implementation (as it seems a bit
first pass).

Just as a question: what happens with the `handle_error()` under normal
usage if I have `DEBUG_PROPAGATE_EXCEPTIONS` set? (It seems like a
probable can of worms…) 🤔
