Wopi edition does not load properly after user office online sign-in : access token being cut on redirection

[mbensoltana]

As part of the business user flow, users will be asked to sign in using their Office 365 credentials. After sign-in, they will be re-directed to the wopi edition screen. However, the Office Online application fails to load because the authentication cookie joined to the "requestURL" as a query param is being cut by the login flow.

please check the eurl as it's clearly cutting original access token param :
