I checked that the new test for this bug (in the current upstream master) passes with this patch from the 20210000.3 source.
I had to do a separate install of the following for my application of mkdocs:
pip install mkdocs-material --user
pip install mkautodoc --user
pip install python-markdown-math --user
because I got no feedback from
dnf info package_name
for each of the package names above.
Tests are done during build process.
