Azure-sdk-for-net: [BUG] BlockBlobClient.CommitBlockList(): “The specified block list is invalid” when committing previously committed blocks

[kevinskii]

Using the Azure.Storage.Blob .NET SDK v12, I'm trying to append to a block blob. When I try to commit a block ID that has already been committed, I get a "400: The specified block list is invalid" error. Per discussion on Stack Overflow, this is supported on the REST API. More details and code to reproduce are at that link.
