See https://github.com/pypa/setuptools/issues/3007#issuecomment-1068621865 where I did a brief analysis and probable explanation.

What it boils down to: Setuptools needs to supply its own copy of distutils aggressively. It provides an opt out for this behavior and is able to offer built in opt out based on whatever signal is available. The default opt out is the SETUPTOOLS_USE_DISTUTILS=stdlib env var. for CPython, it also disables the behavior when ./pybuilddir.txt is present, but installed Pythons probably don’t have this config.

Can those test runners be updated to set this environment variable?
