Cannot set ResponseContentDisposition header with CloudFront presigned url

[rick2ricks]

Hello,

This might be a problem with boto3 or some misconfiguration on my S3 and CloudFront distribution, but maybe someone here knows about this issue. 

When I pass { "ResponseContentDisposition": 'inline; filename="teste.jpg"' to S3Storage url method without using a custom domain ( CloudFront ) , the presigned url works as intended and opens the file in another browser tab, but when I try the same with a custom domain, the parameters are added to the url but CloudFront does not add the content disposition header.

Is it the expected behaviour? If so, how can I use both "content disposition" header set  dynamically when generating the file url with my custom domain?

Thanks
