Chrome 75，打破了变换原点的动画 [英] Chrome 75, break transform-origin animation

问题描述

我在chrome 75版本中发现了可能的问题(或者可能是feature =).变换动画期间变换原点的变化不会影响动画.我附加了snipet，其中包含两个循环，一个循环更改了变换，另一个循环更改了原点.

I found possible issue(or may be it is feature =)) in chrome 75 version. Changes of transform origin during of transform animation doesn't affect on animation. I attached snipet which contains two loops, one changed transform, another changed transform origin.

例如:

在75版本的更新日志中，我发现此提交可能与以下问题有关:提交

In changelog for 75 version I found this commit which probably related to this issue: commit

const div = document.getElementById('div');
const stat1 = document.getElementById('stat1');
const stat2 = document.getElementById('stat2');

// change transform
(function loop(x = true) {
  requestAnimationFrame(() => {
    div.style.transform = x ? 'scale(2)' : 'scale(1)';

    stat1.innerText = div.style.transform;
    stat2.innerText = div.style.transformOrigin;
  });

  setTimeout(loop, 2000, !x);
})();

// change transform origin
(function loop2(x = 0, d = true) {
  div.style.transformOrigin = `${x}% ${x}%`;
  stat3.innerText = div.style.transformOrigin;

  const xx = x + (d ? 1 : -1);
  setTimeout(loop2, 100, xx, xx > 0 && xx < 100 ? d : !d);
})();

#div {
  transform: scale(1);
  transition: transform 4s ease 0s;
}

/* not important */

#div {
  background: green;
  opacity: 0.5;
}

#div2 {
  background: grey;
  color: white;
  text-align: center;
}

#div, #div2 {
  position: absolute;
  top: 80px;
  left: 80px;
  
  width: 80px;
  height: 80px;
}

<div id="div2">
  <span id="stat1"></span><br/>
  <span id="stat2"></span><br/>
  <span id="stat3"></span>
</div>
<div id="div"></div>
