Managed Instance - Start/Stop Schedule and Planned Maintenance (Updates)

Hello Tech-Community,
we recently startet to Shut-Down our Managed Instance over night when all Developers are a sleep.
My question now is - when a [Planned Maintenance] is announced for Updating the Managed Instance Infrastructure, what will happen if the Instance is down with a [Stop Schedule] ?

Will the Patches be applied anyway - or will the Updates fail ?

If anybody knows - please inform us. Thanks.
