    Activate downloads popover when download is completed
    
    When a download is nearly finished, I find myself watching the download
    button, guessing whether the very tip of the download arrow has been
    filled in or not, opening the popover to check if it's ready... and
    repeating if I guessed wrong. Activate when a download completes to
    avoid this.
    
    Not a great final design, it'd be better for the button to glow or
    something, but it's a cheap way to tell the user that the download has
    finished.
