Not collecting an un-paused media element that is not in the Document is correct according to the spec:

    Media elements that are potentially playing while not in a Document must not play
    any video, but should play any audio component. Media elements must not stop
    playing just because all references to them have been removed; only once a media
    element is in a state where no further audio could ever be played by that element
    may the element be garbage collected. [1]

I see that the current code is wrong in that it only considers <audio> elements, I wrote bug 64617 for this.
