Using getPath() with Storage download on S3 with root path

[docmattman]

Possible bug, but maybe I'm doing something wrong???

I'm using an S3 disk with a root option, so I can share a bucket with other disks and have the root prefix for ML:

    [media] => Array
        (
            [driver] => s3
            [key] => MY-KEY
            [secret] => MY-SECRET
            [bucket] => MY-BUCKET
            [root] => media
            ...
        )

This will ensure that all media goes into the /media prefixed folder. Storing and converting media works fine. However, when I want to download a media file using the Storage facade like the following, it fails:

...
$media = $myModel->getFirstMedia();
return Storage::disk('media')->download($media->getPath());

The results of the getPath() is something like this:

media/173/GMbllF6nULTgFqjbdgL0JCpp9bYg9OF0ndJB86qn.jpeg

The media part of the path that is returned is the problem. Since the disk already uses a root path, the download fails. It's basically using media/media/173/GMbllF6nULTgFqjbdgL0JCpp9bYg9OF0ndJB86qn.jpeg because it's already in the root of the S3 disk config.

Is this a bug? Or am I doing something wrong? Any advice for this?
