Wrong indexing of the last element of VectorOfArray

Describe the bug 🐞

julia> a = [[1 2; 3 4], [4 5; 6 7], [7 8; 9 10]]
julia> va = VectorOfArray(a)
VectorOfArray{Int64,3}:
3-element Vector{Matrix{Int64}}:
 [1 2; 3 4]
 [4 5; 6 7]
 [7 8; 9 10]
julia> va[end]
2×2 Matrix{Int64}:
 7   8
 9  10

julia> va.u[end]
2×2 Matrix{Int64}:
 7   8
 9  10

julia> va[:, end]
2×2 Matrix{Int64}:
 4  5
 6  7

Expected behavior

I thought this should be the same no matter whether we are using va[:,end] or va.u[end]?

Reproduce the VectorOfArray example in Julia and compare va[end], va.u[end], and va[:, end]. Trace the indexing behavior responsible for the differing last element, then add or update coverage so the relevant indexing results agree with the intended behavior.
