I'd like to also have 3.13 for testing in https://github.com/gentoo/sci/pull/1292/commits/ee3dd9dc8bca4364f9841deeef9446169ac29905.
I'm sorry to say but pytest-mpl is completely broken by design. It relies on matching output to references images, and these are roughly correct only for very specific freetype version. We specifically build a separate matplotlib instance in src_test() for its own tests, but since matplotlib proper uses system freetype already, other packages (such as pytest-mpl) are broken. In fact, if not for cartopy I would have removed pytest-mpl from ::gentoo already.
