WOPI Infinite loop on Safari when authenticating to O365

When trying to edit an excel document from Nuxeo using the WOPI connector and I am not yet authenticated to Office, it asks me if I want to just download or get authenticated, I click on the authentication option, and then I have an infinite series of redirects between the Nuxeo instance and live.office.com

This happens using Safari. Using Google Chrome everything works fine.

Update : 

tested on safari, intranet : the first connexion and next one do create an infinite loop.
