Research direction

Start at the InProcessInteractiveShell.enable_pylab entry point and inspect how the wrapper passes arguments to IPython 9.0. Reproduce the invalid-kwarg failure and verify that enable_pylab works without the removed welcome_message argument.

Written by the indexing model from the issue text.

Description

The InProcessInteractiveShell.enable_pylab wrapper is broken as of IPython 9.0 as it is explicitly adding the welcome_message kwarg, which was removed in ipython/ipython#14668 after being deprecated for 11 years in ipython/ipython#3568, though no warning was ever raised.
