kvs.ListKeysFiltered returns deleted keys

[kruegernet]

Observed behavior

I create a kv bucket with RF=3 and storage=file
I create a couple of entries, delete them, minutes pass.
Using ListKeysFiltered function on the bucket from application code returns keys of the long (in computer time) deleted keys. This is unexpected.

Expected behavior

Users probably expect ListKeysFiltered will not return deleted keys. Alternatively ListKeysFiltered could take WatchOpt

Server and client version

server 2.10.25, client 1.39.0

Host environment

nats docker image on macos, on applie silicon

Steps to reproduce

Create single node or 3-node cluster
Create a kv bucket with RF=1 or RF=3 and storage=file
Create a couple of entries, delete them, wait a reasonable amount of time (seconds)
Use ListKeysFiltered with empty filter list, or wildcard or globbing filter list.
Receive the keys of recently deleted values from KV
