<video autoplay muted playsinline>
    <source media="(max-width: 800px)" src="http://media.w3.org/2010/05/sintel/trailer.mp4" type='video/mp4'/>
    <source media="(min-width: 801px)" src="https://www.html5rocks.com/en/tutorials/video/basics/devstories.mp4" type='video/mp4'/>
</video>

First video source plays while not matching media query on the desktop.

What is the expected behavior?
Second video source should play, as it matches media query.

What went wrong?
Chromedoes not recognize [media] attribute on the <source> element of the html video

Did this work before? N/A 

Does this work in other browsers? No
 I can reproduce this in the Firefox 63

Chrome version: 71.0.3578.80  Channel: stable
OS Version: 10.0
Flash Version: 

Someone says, that video media query support has been removed from Google Chrome 34+: https://walterebert.com/playground/video/media-queries/

As I can see in the spec, media attribute should be supported: https://www.w3.org/TR/2014/REC-html5-20141028/embedded-content-0.html#attr-source-media
