I just tried again and it seems the annotations work only in Shell but
not in Eshell. This is probably the reason why the issue was missed. In
Eshell the functionality never worked as intended after it got
installed. I didn't mean to exaggerate.

- M-x shell -> Type ls - TAB -> Annotations are displayed
- M-x eshell -> Type ls - TAB -> No annotations
