To fix the same failures on Python 3.9,
they were adjusted in the past. For details see
https://github.com/GrahamDumpleton/wrapt/issues/160
However, Python 3.13 reverted the change from 3.9,
so this adds an upper bound for the conditionals.
To make the conditionals easier to read, the if-else branches were switched.
