No parentheses around word-like operators?

Odoc generated HTML output seems to be not parenthesizing operators which have word-like characters inside them. Eg https://ocaml.org/p/lwt/latest/doc/Lwt_result/Syntax/index.html

This is formatted as:

```ocaml
val let* : ('a, 'e) t -> ('a, ('b, 'e) t) -> ('b, 'e) t
```

Shouldn't it be:

```ocaml
val ( let* ) : ('a, 'e) t -> ('a, ('b, 'e) t) -> ('b, 'e) t
```

?
