Muted autoplay videos stop playing in Safari 11.0

Question

I have these videos on my site with attributes listed below:

<video width="100%" poster="poster_url.png" autoplay loop muted playsinline>
<source src="video_url.mp4" type="video/mp4">
</video>    

Everything worked just fine until I’ve installed Safari 11. This version shows poster images and does not autoplay videos even though they don't have an audio track. Take a look at it on my site.

I saw autoplay videos working on other sites (even without muted property) on my own laptop in Safari.

Any help would be greatly appreciated!

Yup, it appears Safari is also blocking muted video's (that don't even have sound)...

I have found a workaround, but it isn't pretty and I'm not proud of it:

var ua = navigator.userAgent.toLowerCase();
var is_safari = (ua.indexOf("safari/") > -1 && ua.indexOf("chrome") < 0);
if(is_safari) {
    var video = document.getElementById('#video-element-id');
    setTimeout(function() {
       video.play();
    }, 50);
}                       

I have tried doing this without the timeout, but Safari is rejecting this by throwing a Promise rejection. I don't know why...
