Authentication dialog not closing in Office Online on IE11(11.706.17134.0)

[jorgenho]

We have run into an issue with a specific version of IE11 (11.706.17134.0), where the dialog does not close after redirect. It works fine on every other platform/browser/version.

Error when closing dialog manually:
