Protect passwords with enhanced phishing protection

We are seeing the "Password reuse is a security risk" prompt from this feature when entering our passwords in Microsoft OAuth-based authentication prompts at URLs starting with "login.microsoftonline.com/common/oauth2/v2.0/authorize"

We get it consistently with one of our vendors, who we have integrated authentication via OAuth, and then in fact just saw it again logging into my work Microsoft account to post this comment on this page.

Is there a way to add a site to an exclusion list for the "Password reuse" feature? Although it seems Microsoft should have this domain globally allowed unless I am mistaken on how this is intended to work.
