CosmosDB.Account GET API doesn't return createMode when capabilities is set and API version is 2021-10-15

Recently we found CosmosDB.Account GET API doesn't return createMode anymore when capabilities is set and API version is 2021-10-15. But the API behavior is different than before since previously CosmosDB.Account GET API can return createMode when capabilities is set and API version is 2021-10-15. Seems it's a regression issue. So could you take a look and fix it asap? Thanks.

Use the CosmosDB.Account resource and API version 2021-10-15 from the reported PUT request as the entry point, then inspect how the corresponding GET response is specified when the capabilities array contains EnableTable. Compare the request and response payloads, especially createMode. Done means a GET response preserves createMode under this condition and a regression check covers it.
