When I use my package regularly, a data type is shown like this:

```julia-repl
julia> using PDBTools

julia> ats = read_pdb(PDBTools.TESTPDB)
   Vector{Atom{Nothing}} with 62026 atoms with fields:
   index name resname chain resnum residue x y z occup beta model segname index_pdb
       1 N ALA A 1 1 -9.229 -14.861 -5.481 0.00 0.00 1 PROT 1

```

where we see `Vector{Atom{Nothing}}` as the type of the array.

Now, I have `jldoctest` which is identical to the above, but the test fails because it expects `Vector{PDBTools.Atom{Nothing}}` instead:

```julia
│ diff =
│ Vector{Atom{Nothing}} Vector{PDBTools.Atom{Nothing}} with 72 atoms with fields:
│ index name resname chain resnum residue x y z occup beta model segname index_pdb
│ 1 N ALA A 1 1 -9.229 -14.861 -5.481 0.00 0.00 1 PROT 1

```

Why is the type printed differently in the `jlsdoctest` vs. regular usage of the package, and how that can be solved?

Thanks.

Additional info: This incongruity happens on the CI run, but not when I run `doctests` locally. I can even run `doctests(PDBTools; fix=true)` and all works locally, but these tests fail on the CI execution.

edit: The issue is when running this as part of the test suite of the package:

```julia
@testitem "Doctests" begin
    using Documenter: doctest
    using PDBTools # with or without this
    doctest(PDBTools)
end

```

Thus, I’ll just remove that from the test suite. But I wonder which is the scoping issue that’s causing the types to be printed differently in each case.
