The failures can be seen for example on: #163903

Or reproduce locally:

flutter test /usr/local/google/home/jmccandless/Projects/flutter/packages/flutter/test/material/reorderable_list_test.dart --test-randomize-ordering-seed=20250221

This is due to a test flake that was fixed in #161836, but that fix was not included in the stable release branch. I am cherry-picking it in #164050.

A prior attempt to fix this problem was: #163903
