Re: [csswg-drafts] [css-borders-4] Allow to define separate border images for different border regions (#9183)

Potential live site use cases for this change to `border-image-source`. It is of note that there are many more examples of border-image like styles on this page than I've called out below but I don't see `border-image` being used at all: https://baldursgate3.game/

1. Around the entire element we have mirrored corners and a top edge mirrored to the bottom edge, and I guess right and left mirrored as well even though it's just a solid line.

```css
border-image-source: url('corner.svg') url('top-bottom-edge.svg') url('left-right-edge.svg');
```

2. Child call to action button is similar except without a right or left edge. So maybe?:

```css
border-image-source: url('corner.svg') url('top-bottom-edge.svg') none;
```
