julia> using ArrayInterface
julia> A = rand(5,12);
julia> B = reshape(A', (3,4,5));
julia> ArrayInterface.strides(B) # @chriselrod: should be `(5,15,StaticInt{1}())`
(static(1), 3, 12)

Research direction
Reproduce the Julia example from the issue using ArrayInterface.strides on the reshaped adjoint array B. Trace the strides implementation and its handling of reshape and transpose, then verify that the result is (5, 15, StaticInt{1}()) for the reported case.
