Wrong results using argmin or argmax

[doraut]

Using argmin or argmax along a dimension of an OffsetArray gives wrong results for some offsets
Examples:

using OffsetArrays
A = [1 2; 1 2]
for offset in 0:-1:-3
    A_off = OffsetArray(A, offset, -1)
    A_off[argmin(A_off, dims=2)] |> println
end

produces

[1; ; 1] # Correct
[2; ; 1] # Wrong
[1; ; 2] # Wrong
[1; ; 1] # Correct
