Version issues

I've observed issues where figures don't appear when they should, basically it looks like plt.ion() hasn't been called, even though plt.isinteractive() is True and says it has. Essentially the matplotlib event loop is not properly connected into IPython. This seems to be highly dependent on the versions of Python, IPython and Matplotlib.

Combinations that I know work are:

Python	IPython	Matplotlib
3.9.	8.8.	3.6.2
3.10.16	8.31.0	3.10.0

Note that the recent versions of IPython require Python 3.10 or better.
