`locate-type` brings me to wrong type

In https://github.com/ocaml/ocaml-lsp/blob/master/submodules/lev/lev-fiber/src/lev_fiber.ml#L1253, the type of loop is Lev.Loop.t, but locate-type brings me to Nonempty_list.t.

I am not even able to jump at all in these files due to a configuration issue. My guess is that this is due to the copy_file stanza that is not correctly handled by merlin. We should have a way for Dune to communicate the copying of files to Merlin so that jumping works as expected.
