Difficulty writing into array (unsure if intentional)

Trying to write into an array gives an error when one of the arrays has a trailing singleton dimension:

julia> table(:, :total) .= sum(pointwise([:loo_score, :naive_score, :overfit]); dims=1)'
ERROR: DimensionMismatch("cannot broadcast array to have fewer dimensions")

Where table(:, :total) and sum(pointwise([:loo_score, :naive_score, :overfit]); dims=1)' return:

1-dimensional KeyedArray(NamedDimsArray(...)) with keys:
↓   criterion ∈ 3-element Vector{Symbol}
And data, 3-element view(::Matrix{Float64}, :, 1) with eltype Float64:
 (:loo_score)    2.5e-323
 (:naive_score)  5.0e-323
 (:overfit)      7.4e-323


2-dimensional KeyedArray(NamedDimsArray(...)) with keys:
↓   statistic ∈ 3-element Vector{Symbol}
→   data ∈ 1-element OneTo{Int}
And data, 3×1 adjoint(::Matrix{Float64}) with eltype Float64:
                  (1)
  (:loo_score)     69.38414329944844
  (:naive_score)  218.93276111448398
  (:overfit)      149.54861781503556

This can be left (which would be consistent with Base), or trailing singleton dimensions could be fixed for ease-of-use.

Start by reproducing the reported assignment with the shown 1-dimensional and 2-dimensional KeyedArray values, then compare the behavior with Base broadcasting. The issue names no files or tests; completion requires deciding whether trailing singleton dimensions should be normalized or whether the current DimensionMismatch should remain.
