When I elementwise multiply an offset array by a regular array, I get the result I expect - the resulting array is offset properly - except when the size is 1.
In this example, the input array dimension is 6:10, and the multiplication result is 6:10 in the first dimension. This is as I expect, and all dimensions of size greater than 1 result in the same first dimension as the input.
rp
5-element OffsetArray(::Vector{Float64}, 6:10) with eltype Float64 with indices 6:10:
1.3901009231535904e17

csmlon
1×2 adjoint(::Vector{Float64}) with eltype Float64:
-0.594981 0.80374
rp .* csmlon
5×2 OffsetArray(::Matrix{Float64}, 6:10, 1:2) with eltype Float64 with indices 6:10×1:2:
-8.27084e16 1.11728e17
-1.55762e20 2.10414e20
-1.88473e23 2.54602e23
-1.59496e26 2.15458e26
-8.43591e28 1.13958e29
However, when the input array is 10:10, the multiplication result is 1:1 in the first dimension. I expect 10:10 as the first dimension, consistent with the size > 1 case.

The only resolution I can think of is to call OffsetArray(...) on the result in the size=1 case. Is this a bug?
