Result in Safari

As noticed by ana tudor, while the code below works in Safari (meaning it renders , it does not in GTK

```
<style>
  div {
    border: solid 6em transparent;
    width: 4em;
    aspect-ratio: 1;
    background:
    linear-gradient(in hsl longer hue, red 0 100%) border-area;
  }
</style>
<div>&nbsp;</div>
```
