It is fixing a performance regression introduced in #98025 under AArch64. My only worry in it is the sorting algorithm, where there is a chance it isn't quite strict-weak. The regression wasn't huge, lets leave this one and we can pick it up in the next release. It's a bit of a shame to get the decreased performance but it might be better to be careful, considering this was already wrong once.
