Edge profiles not fully isolated — accounts from one profile visible in another

I’m using Microsoft Edge with two separate profiles, each signed in with a different Microsoft/Azure AD account and syncing independently. Sync works fine, but I noticed something odd:

When I’m in my second profile, I can still see the account from my first profile listed as an available sign-in option (and vice versa). It seems that all accounts I use in Edge show up in every profile, even though I only want each account to exist in its own profile.

From my understanding, profiles should be isolated, but it looks like Edge (or Windows) is pulling all accounts from a shared system account store. This isn’t ideal for me, as I want strict separation between profiles.

My questions:

Is there a way to prevent accounts from one profile showing up in another?

Can Edge profiles be configured to not share the same system account list?

Is this behavior by design, or am I missing a setting somewhere?

I’m on Windows 11, latest version of Edge.
