Anyone can feel free to try to fix the issue here. Not sure I'll get back to it in a while. At least it is rebased, so slightly easier...

Marking this as good first issue b/c it's building on an existing patch that's rebased against current code & has clear next steps - figure out why the tests aren't passing and make them pass. To work on this you can either copy @oscargus's work or open a pull request against this branch on his fork of matplotlib. You can also suggest solutions as part of reviewing this PR.

The easiest way is probably to create your own branch from this, leading to something like:

git remote add oscargus https://github.com/oscargus/matplotlib.git
git fetch oscargus
git switch -c mybranch remote/oscargus/sketch-seed

(If this is not the correct branch name, check with git branch -v -a.)

I think this one has been superseded by #26050. Please re-open if I’m mistaken.
