Cloudformation deletion deleting the S3 bucket in spite of DeletionPolicy:

Question

I have a cloud formation template with the following, if I delete the stack the bucket still gets deleted even though the bucket DeletionPolicy is Retain.  
  
Resources:  
  mybucket123:  
    Type: 'AWS::S3::Bucket'  
    DeletionPolicy: Retain  
    Properties: {  
      AccessControl: Private  
      PublicAccessBlockConfiguration:  
        BlockPublicAcls: true  
        BlockPublicPolicy: true  
        IgnorePublicAcls: true  
        RestrictPublicBuckets: true  
      BucketEncryption:  
        ServerSideEncryptionConfiguration:  
          - ServerSideEncryptionByDefault:  
              SSEAlgorithm: AES256  
      VersioningConfiguration:  
        Status: Enabled  
        }  
Outputs:
