Impossible to add YouTube/Vimeo controls via .controls() method?

[djvs]

This patch was manually added into current stable popcorn-complete.js (to mimic future popcorn-complete releases):

https://github.com/mozilla/popcorn-js/pull/441/files?diff=split

such that Vimeo and YouTube methods all work (Popcorn.youtube, Popcorn.HTMLYoutubeVideoElement, etc.). Player starts and stops correctly on click. However, all video controls are missing, and calling popcorn.controls(true) has no effect, for:

            // "vidid", "vidurl", "elemid" all valid
            var vidurl = "http://player.vimeo.com/video/" + vidid;
            var player = new Popcorn.HTMLVimeoVideoElement("#"+elemid);
            player.src = vidurl;
            player = new Popcorn(player);
            player.controls(true);

Going into inspector and manually adding "controls" attribute to the video element inside the iframe does, however, enable the controls. Shouldn't adding it be a fallback for these wrappers or something similar? My only alternative is DOM manipulation inside the iframe...
