Bug: "Error: comment ... dropped" on trailing comment with disabled ocamlformat

[vog]

This program:

[@@@ocamlformat "disable"]
let test = "test"
(* test *)

causes ocamlformat to output the following error message:

ocamlformat: Cannot process "...".
  Please report this bug at https://github.com/ocaml-ppx/ocamlformat/issues.
  BUG: comment changed.
File "...", line 3, characters 0-10:
Error: comment (*  test  *) dropped.

where .ocamlformat contains:

profile = conventional
version = 0.28.1

And yes, strangely the first line [@@@ocamlformat "disable"] is actually necessary to reproduce this bug.

As a side note, an even shorter way to reproduce this error is:

[@@@ocamlformat "disable"]
(* test *)
