AWS::SQS::QueuePolicy Bug resolving dynamic references in Condition statement

2. Scope of request
Dynamic reference is not being resolved within the "Condition" section. instead, the text is displayed in the policy.

3. Expected behavior

It should lookup the secret

4. Test case recommendation
The following template section does not resolve the secret.
```
QueuePolicy:
Type: AWS::SQS::QueuePolicy
Properties:
PolicyDocument:
Statement:
- Effect: Allow
Action:
- "sqs:SendMessage"
Principal:
AWS: '*'
Resource: !GetAtt Queue.Arn
Condition:
ArnEquals:
"aws:SourceArn": !Sub "{{resolve:secretsmanager:/${Environment}/${Region}/topics:SecretString:MyTopicArn}}"
Queues:
- !Ref Queue
```
I've not checked if its specific to a Condition statement or specific to QueuePolicy
