Delta request for sites doesn't return the correct ID of the site, only a subset

I am using the latest version (2.3.0), and I want to get the list of all sites.

When I use the classical SitesRequestBuilderGetRequestConfiguration and invoke

$response = $context->sites()->get($configuration)->wait();

I get the correct set of values - instances of \Microsoft\Graph\Generated\Models\Site where ids of all the listed sites conform to the full specification of "Site collection hostname, Site collection unique ID, Site unique ID".

When I use DeltaRequestBuilderGetRequestConfiguration and invoke

$context->sites()->delta()->get()->wait()

all the instances of \Microsoft\Graph\Generated\Models\Site look identical, with the exception of the id field, which is suddenly truncated to the Site unique ID only. (Which isn't really unique globally, only within a certain site collection.)

The official documentation is a bit unclear on this. The example for obtaining the whole set clearly indicates that full ids should be returned:

"id": "contoso.sharepoint.com,da60e844-ba1d-49bc-b4d4-d5e36bae9019,712a596e-90a1-49e3-9b48-bfa80bee8740",

but the "Removed" response only indicates the Site unique ID only.

"id": "bd565af7-7963-4658-9a77-26e11ac73186",

Without consistent behavior, the delta requests will be unusable.

Inizia riproducendo le due chiamate mostrate nell’issue: SitesRequestBuilderGetRequestConfiguration e la richiesta delta dei sites. Confronta gli ID dei Site restituiti con la documentazione di Microsoft Graph su site-delta, incluso l’esempio di risposta removed. Il lavoro è completo quando il comportamento dell’SDK è stato corretto oppure l’incoerenza dell’API è stata confermata e documentata chiaramente.
