> Is there any sorting order between JS object keys?
I'm not sure which part you're referring to but both the order in which the keys are read off the objects is specified, as is the order in which they are resolved when they overlap.

My concern is that will mean that code like the following won't work:
```js
const anim = elem.animate({ MozTransform: 'translate(100px)' }, 1000);
// Update target translation to 200px
anim.effect.setKeyframes({
...anim.effect.getKeyframes()[0],
MozTransform: 'translate(200px)'
});
```
(since the initial `MozTransform` will be transformed into `transform` which will override the new `MozTransform`).
It also means that code like the following will stop working when we unprefix '-moz-user-select' (as just happened):
```js
const initialValue = anim.effect.getKeyframes()[0].MozUserSelect;
```
