Sometimes not being offered to save credentials

I was thinking perhaps it was because bitwarden was not unlocked, but I seem to remember(and correct me if I’m wrong) that if you’re bitwarden is locked, you are still offered to save the credentials, only then you’re prompted to unlock bitwarden.

Is that not how it works? It seems like sometimes it offers to remember the credentials and sometimes it does not.

I’m using this on the Brave browser if that matters. It’s all Chromium so I doubt it.
