Indexing vector of variables has strange repr

[jariji]

What is this (xs[1])[1:3] supposed to mean?

julia> @variables xs[1:3]::Vector{LiteralReal} ys[1:4]::Vector{LiteralReal}
2-element Vector{Symbolics.Arr{Symbolics.Arr{Num, 1}, 1}}:
 xs[1:3]
 ys[1:4]

julia> xs[1]
(xs[1])[1:3]


(@main) pkg> st Symbolics
