Fn::Join not accepting a Ref to a CommaDelimitedList as an array argument

[grams]

Given this YAML template:

---
AWSTemplateFormatVersion: '2010-09-09'
Description: "Sample !Join and !Ref usage"
Parameters:
  aliasesParameter:
    Type: CommaDelimitedList
    Description: Comma separated list of domain names
Resources:
  MyDistribution:
    Type: AWS::CloudFront::Distribution
    Properties:
      DistributionConfig:
        Comment: !Join [ ", ", !Ref aliasesParameter ]

The expression !Join [ ", ", !Ref aliasesParameter ] is highlighted as an error "Join expects a string argument and an array argument". However, the reference to a CommaDelimitedList is, indeed, an array (of strings), AFAICT.
