Due to a priority shift this request has slipped to the backlog. I hate to bring bad news. I will continue to provide the feature team your feedback and votes.
Hopefully this will move back up in the queue soon.

I agree, the website tab needs to stay where it was last at, with a home button and back forward buttons. It should really be what effectively amounts to a permanent Edge tab.
We are still considering this feature for future releases, and will continue to update the status when it changes.
Thanks to everyone who volunteered for testing the Office 365 group calendar. The TAP team will be reaching out as we are closer to being ready.
