Description

When there are multiple equal elements that could have their index returned, the one with the smallest index is supposed to be returned. But it isn't always.

Reproduction Steps

using System.Numerics.Tensors;

ReadOnlySpan<float> floats = [10f, -20f, -30f, 1f, 1f, -40f];
Console.WriteLine(TensorPrimitives.IndexOfMinMagnitude(floats));

or

using System.Numerics.Tensors;

ReadOnlySpan<float> floats = [10f, 20f, 30f, 1f, 1f, 40f];
Console.WriteLine(TensorPrimitives.IndexOfMin(floats));

Expected behavior

Those should both print 3.

Actual behavior

They print 4.
