I created a CloudFormation stack using the template below via Boto3 Python method `cf_client.create_stack(StackName="test")`; however, when I attempt to call `s3_client.get_bucket_policy(Bucket="my-bucket")` I receive a `NoSuchBucketPolicy ... The bucket policy does not exist` error. 

```yaml

Description: A sample template

Resources:
  TestBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: my-bucket
      AccessControl: PublicRead
      BucketEncryption:
        ServerSideEncryptionConfiguration:
          - ServerSideEncryptionByDefault:
              SSEAlgorithm: AES256

  TestBucketPolicy:
    Type: AWS::S3::BucketPolicy
    Properties:
      Bucket:
        Ref: TestBucket
      PolicyDocument:
        Id: TestBucketPolicy
        Statement:
          - Action:
              - "s3:GetObject"
            Effect: "Allow"
            Resource:
              Fn::Join:
                - ""
                - - "arn:aws:s3:::"
                  - Ref: TestBucket
                  - "/*"
            Principal: "*"
            Condition:
              StringLike:
                aws:Referer:
                  - "http://www.example.com/*"
                  - "http://example.com/*"
```

Is this something that's supported? 

Thanks in advance.
