[Bug]: PDF files uploaded to S3 using the disk() method are corrupted

[danatemple]

What happened?

I used the ->disk() method to upload to S3, but when I do this I can see that the file has double the expected size, and does not parse as a valid PDF.

How to reproduce the bug

This process, where I generate a PDF file locally and then manually copy to S3, works:

                Pdf::view('messages.da.invite', $params)
                   ->save($localFilePath);

                $contents = file_get_contents($localFilePath);

                $disk->put($filePath, $contents);

This version fails.

              Pdf::view('messages.da.invite', $params)
                  ->disk($diskName)
                  ->save($filePath);

The file is created, but I can see that it is twice the expected size on S3 and that on copying back from S3, it fails to parse.

$filePath is the path on S3 from the bucket root. $diskName is the string key from config('filesystems.disks') - I expected actually to be able to pass an actual disk instance ($disk), but this did not work.

Hope I am not missing something obvious here!
