Did Chrome / Safari recently change the way mix-blend-mode is handled

问题

I made a webpage a couple of weeks ago, using the (then) recent version of Chrome (probably v56 or v57 but i dont know for sure), Safari and Firefox during development (on OSX). http://dirkluetter.de/projecttype/kamera

Firefox (v52 & v53) still displays the Page as intended.

While the most recent Chrome version (v58) does not anymore.

I used mix-blend-mode and background-blend-mode CSS properties which worked fine then - and still do on FF. Now Chrome / Safari seem to ignore the property, while Firefox still displays the page as intended. Did something change recently in the way Webkit browsers handle mix-blend-mode? i cant find any infos regarding a change on this ... there are several other questions regarding mix-blend-modes and chrome but the ones i checked where not related to mine.

I'm not sure exactly what's going on, but I can get it to work in Chrome by adding background: white to the root element and moving the mix-blend-mode to a wrapper element inside of body.

html {
  background: white;
  display: flex;
  height: 100%;
}

body {
  margin: 0;
  background-blend-mode: luminosity;
  background-image: url(https://upload.wikimedia.org/wikipedia/commons/1/15/AreeiroMetroLx2.JPG);
  background-color: #006699;
  background-size: cover;
}

div {
  mix-blend-mode: multiply;
}

p {
  color: magenta;
}

<div>
