Unable to open files with Office Online

When clicking e.g. "Open with Microsoft Online Excel" on a file from the Dropbox website, a loading page shows and then it just ends up becoming a blank page. It used to work, but it seems there's a security policy in the headers on the page preventing communication with Microsoft login services, as the JavaScript console shows the following error:

Refused to send form data to 'https://login.live.com/' because it violates the following Content Security Policy directive: "form-action 'self' https://docs.google.com/document/fsip/ https://docs.google.com/spreadsheets/fsip/ https://docs.google.com/presentation/fsip/ https://docs.sandbox.google.com/document/fsip/ https://docs.sandbox.google.com/spreadsheets/fsip/ https://docs.sandbox.google.com/presentation/fsip/ https://excel.purple.officeapps.live-int.com https://onenote.purple.officeapps.live-int.com https://powerpoint.purple.officeapps.live-int.com https://visio.purple.officeapps.live-int.com https://word-view.purple.officeapps.live-int.com https://word-edit.purple.officeapps.live-int.com https://officeapps-df.live.com https://excel.officeapps-df.live.com https://onenote.officeapps-df.live.com https://powerpoint.officeapps-df.live.com https://word-view.officeapps-df.live.com https://word-edit.officeapps-df.live.com https://officeapps.live.com https://excel.officeapps.live.com https://onenote.officeapps.live.com https://powerpoint.officeapps.live.com https://word-view.officeapps.live.com https://word-edit.officeapps.live.com https://paper.dropbox.com/cloud-docs/edit https://www.dropbox.com/ https://dl-web.dropbox.com/ https://photos.dropbox.com/ https://paper.dropbox.com/ https://showcase.dropbox.com/ https://www.hellofax.com/ https://app.hellofax.com/ https://www.hellosign.com/ https://app.hellosign.com/ https://help.dropbox.com/ https://navi.dropbox.jp/ https://selfguidedlearning.dropboxbusiness.com/ https://instructorledlearning.dropboxbusiness.com/ https://sales.dropboxbusiness.com/ https://accounts.google.com/ https://api.login.yahoo.com/ https://login.yahoo.com/ https://pal-test.adyen.com https://2e83413d8036243b-Dropbox-pal-live.adyenpayments.com/".

Is there some configuration we need to do on our end to get this working again?
