Attachment suggestion does not show entities context

Reproduction steps

1. create page A
2. create page B.C
3. upload an attachment on page C
4. edit page A with blocknote
5. search for the name of the attachment on page C
6. observe the suggestions

Expected

Each suggested attachment is precisely contextualized with its hierarchy (list of parents)

Actual

Only "C" is displayed, with no indication of the parent pages.

Note

Also, when selecting an entry from the auto-suggest choices, only the name of the selected page ID is displayed (instead of the full reference).
This is not the case when editing back the link though.
This is the equivalent of CRISTAL-619 which is about links suggestion.
