scroll-behavior not working on IOS' Safari

I'm using polyfiller to allow the use of scroll-behaviour and it work great on MacOS safari but on IOS it not doing anything not even scrolling

```js
<script crossorigin src="https://polyfill.app/api/polyfill?minify&sourcemap&features=scroll-behavior"></script>

....

target.scrollIntoView({
  behavior: 'smooth'
})
```
