>From memory, we began implementing this in Firefox but never finished it. It's complicated by the fact that you can also animate the `writing-mode` etc. so that part-way through the animation the mapping for the properties changes, e.g.
```css
#element {
margin: 50px 100px;
animation: yer 5s;
}
@keyframes yer {
to { margin-inline-start: 200px; writing-mode: vertical-lr; }
}
```
As a result you can't just do the mapping to physical properties when you set up the animation. Instead you need to re-evaluate the mapping whenever the _animated_ value of the `writing-mode`, `direction` etc. change.
