I confirm that my issue with raise ValueError() from ValueError() has been fixed as well in 8.2.

lestevecommented, Feb 10, 2022

FWIW a git bisect points to #11886 which uses stack_data to show the stacktrace.

I tried to see whether that was a regression in stack_data but actually I get the same behaviour for all the available stack_data versions.

To reproduce in a fresh environment:

conda create -n test-env ipython -y 
conda activate test-env
ipython -c 'raise ValueError("error") from ValueError("cause")'
