Description: gh-91457 changed the behavior of auto() in case of mixed type Enums. the fallback behavior (before deprecation) was supposed to be backwards compatible (I think), but iterating the sorted last_values in order (instead of reversed order) results an incorrect behavior of always reusing values after the first auto(), as demonstrated in the test case I extended in this PR. Issue: gh-104271
