Can't sign in with Microsoft through Confluence in Safari

[Marlon]

I got access to a Confluence document that has a OneDrive sub page that holds a PowerPoint doc to which it asks me to sign in to view. I click the Microsoft sign in button and a popup appears with some text about being signed in and them closes itself. However, the Microsoft page never updates and I can't see the document. Just the Sign in page remains. I try refreshing the page, but to no avail. Anyone know how to solve this? It works in Chrome.

Unchecking "Prevent cross-site tracking" in Safari's Settings (Privacy tab > Website Tracking) allowed it to work.

It's a bummer that has to be unchecked for that feature to work.
