Random doctest failure in structure/coerce_actions.pyx

[jhpalmieri]

Steps To Reproduce

OS X 13.4.1 on Apple M1. ./sage -t --long src/sage/structure/coerce_actions.pyx typically passes, but with a specific random seed, I get failures:

./sage -t --long --random-seed=59996678553091503109319269785176095170 src/sage/structure/coerce_actions.pyx

fails as described below.

Expected Behavior

Doctests should pass.

Actual Behavior

./sage -t --long --random-seed=59996678553091503109319269785176095170 src/sage/structure/coerce_actions.pyx

fails:
