Ambiguity error when running copyto!

[gaurav-arya]

MWE:

julia> a = ApplyArray(vcat, [1], [2])
vcat(1-element Vector{Int64}, 1-element Vector{Int64}):
 1
 2

julia> b = ApplyArray(vcat, [1], [2])
vcat(1-element Vector{Int64}, 1-element Vector{Int64}):
 1
 2

julia> a .= b
ERROR: MethodError: _copyto!(::LazyArrays.ApplyLayout{typeof(vcat)}, ::LazyArrays.ApplyLayout{typeof(vcat)}, ::ApplyArray{Int64, 1, typeof(vcat), Tuple{Vector{Int64}, Vector{Int64}}}, ::ApplyArray{Int64, 1, typeof(vcat), Tuple{Vector{Int64}, Vector{Int64}}}) is ambiguous.

Candidates:
  _copyto!(::Any, LAY::LazyArrays.ApplyLayout{typeof(vcat)}, dest::AbstractArray{<:Any, N}, V::AbstractArray{<:Any, N}) where N
    @ LazyArrays ~/.julia/packages/LazyArrays/NYra8/src/lazyconcat.jl:237
  _copyto!(::LAY, ::LAY, dest::AbstractArray{<:Any, N}, src::AbstractArray{<:Any, N}) where {LAY<:LazyArrays.ApplyLayout, N}
    @ LazyArrays ~/.julia/packages/LazyArrays/NYra8/src/lazyapplying.jl:333

Possible fix, define
  _copyto!(::LazyArrays.ApplyLayout{typeof(vcat)}, ::LazyArrays.ApplyLayout{typeof(vcat)}, ::AbstractArray{<:Any, N}, ::AbstractArray{<:Any, N}) where N
