Get DriveItem sharing permission does NOT return User information with whom the Item was shared (OneDrive Live account) #2828
Description
Describe the bug
My application use C# MsGraph SDK and executes await graphClient.Drives["{drive-id}"].Items["{driveItem-id}"].Permissions.GetAsync() to get sharing permission of item in OneDrive Personal\Live account. This information is used later to detect access rights to the Item for current session user (returned by await graphClient.Me.Request().GetAsync()).
Earlier, MsGraph returned in this request the user information (including Id) in User facet with whom the Item was shared.
The code was stable for long time.
But now MsGraph does not return this information anymore, User facet is null. Only SiteUser facet is present, but it contains other Id that is not equal with Microsoft Graph User Id.
The sharing permission request returns only SiteUser facet that is SharePoint Identity only
Expected behavior
User face should contain user information (at lease user Id).
How to reproduce
Execute graphClient.Drives["{drive-id}"].Items["{driveItem-id}"].Permissions.GetAsync() for shared with me Item in OneDrive Presonal\Live account.
See User facet in response.
