Edge Password Manager Suggests Saved Passwords Across Different Subdomains

Description:

Microsoft Edge suggests saved credentials from a.example.com when I focus a password field on b.example.com.

These are separate websites with different authentication systems. I expect saved credentials to be matched against the exact hostname by default, rather than being suggested across sibling subdomains.

Expected behavior:

Credentials saved for a.example.com should not be suggested on b.example.com by default.

Users should be able to configure strict hostname matching while retaining password autofill for each site.

Feature request:

Please provide an option to disable cross-subdomain credential suggestions in Microsoft Edge Password Manager.
