To get this to work, it looks like we should either increase the tolerance on test_asterisk_marker and drop the stuff that checks request, or backport #15199.

I vote backport, it is testing details, not user-facing so it is OK.

xref #16795

Thanks for this fix! Broken marker tuples are currently impacting my packages, is there a timeline when 3.2.1 will be on pypi? In the meantime I guess I'll pin my versions to 3.1.2

Well, it's good to see someone uses it, and fixing it by chance was useful. Please consider adding Framework :: Matplotlib to your PyPI classifiers on kwplot.

3.2.1 is planned for tonight.
