    Missing attachment button for attachments of a known type
    
    If there was a known formatter for the attachment's mime type, the attachment
    content was shown inline, without the attachment button, instead of it being
    shown collapsed and with the corresponding button. All that caused by a variable
    overwrite and a related memory leak.
