I am using an HTML5 video tag as follows:
<video playsInline muted autoPlay className='video' preload='auto' loop='loop'>
<source src="intro-m-no-audio.mp4" type='video/mp4' />
</video>
As you can see, the muted attribute is set. Also, I made sure the video doesn't have any more audio track:
avconv -i intro-m.mp4 -vcodec copy -an intro-m-no-audio.mp4
this gives:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'intro-m-no-audio.mp4':

As you can see, there is no more audio stream present.
YET, everytime I open the page on Android Mobile Firefox (v53), my Spotify player stops playing and an annoying video "notification" appears. That doesn't happen in Chrome (on Android). How can I prevent this?
EDIT: Here's the live example to see what I mean: https://www.srf.ch/static/srf-data/data/2017/pendler/#/de
