These is a case we crash because we didn't build an identity matrix for InterpolateMatrix:

  <style>
    #target {
      width: 100px;
      height: 100px;
      background-color: blue;
      transition: all 10s linear;
      transform: translateX(100px);
    }
  </style>
  <script>
    var div = document.getElementById('target');
    div.style.setProperty("transform", "rotate(60deg)", "");
    window.getComputedStyle(div).transform;
    div.style.setProperty("transform", "none", "");
  </script>
  <div id="target"></div>

We might trigger an transition from an InterpolateMatrix to none, so panic [1].

I think we've been using P1 for stability issues like this.
Priority: P2 → P1
