This is indeed annoying.
Unfortunately, and quite surprisingly to me, using -o /dev/stdout does
not help.

I've seen a comment in a record initialization (to comment on
a given field) moved far away, after the end of the record.
Here is an exemple :
---
type record = { a : int; b : int; c : int }
let r1 = {
a = 0 ;
b = 1 ; (* This is about b *)
c = 2 }
---
where the comment disapear. While in this one :
---
type record = { a : int ; b : int ; c : int }
let r1 = {
a = 0 ;
b = 1 ; (* This is about b *)
c = 2 } and
r2 = { a = 0 ; b = 1 ; c = 2 }
---
the comment is moved after initialization of r1. :-(
