Doesn't this happen already? AFAIK, unless you force it, styles are not applied synchronously.
For example, if I go to https://drafts.csswg.org/cssom/ and run
```js
for (let i = 0; i < 100; ++i) {
document.body.style.width = Math.random() * 1000 + "px";
document.body.offsetLeft;
}
```
it takes like 8 seconds, because I'm forcing layout at each iteration. But if I remove the `offsetLeft` line, it's a single millisecond.
