`collect(Iterator.product(offset arrays))` is an OffsetArray but `collect (offset_array)` is not

So here is a weird thing:

julia> Iterators.product(OffsetArray(rand(3), -1:1), 1:2) |> collect
3×2 OffsetArray(::Matrix{Tuple{Float64, Int64}}, -1:1, 1:2) with eltype Tuple{Float64, Int64} with indices -1:1×1:2:
 (0.892917, 1)  (0.892917, 2)
 (0.398366, 1)  (0.398366, 2)
 (0.550785, 1)  (0.550785, 2)

julia> collect(ans)
3×2 Matrix{Tuple{Float64, Int64}}:
 (0.892917, 1)  (0.892917, 2)
 (0.398366, 1)  (0.398366, 2)
 (0.550785, 1)  (0.550785, 2)

Since collect promises an Array not an AbstractArray I am thinking that the first return is wrong. But I think this should probably be consistent at least. At least I would assume that collect(collect()) == collect

Reproduce the discrepancy using Iterators.product with an OffsetArray, then compare it with collect applied to an already collected OffsetArray. Read the collect behavior involved in these two cases and determine which result should satisfy the stated Array and consistency expectations. Done means the behavior is consistent and covered by an appropriate regression test.
