Re: [csswg-drafts] [css-borders][css-tables] Define how listified borders collapse (#13410)

I guess we should first ask what the rendering for border-collapsed multi-border should look like even if there is no conflict, in the simplest of cases.

For example, consider this:

```
td {
    border: 15px solid green,
    border: 15px solid blue,
    border: 15px solid red;
}
```
Should the result look something like this?

<img width="1002" height="447" alt="Image" src="https://github.com/user-attachments/assets/c87c3a48-0310-41ae-9abb-8a4d08b2949a" />


Or maybe this?

<img width="999" height="442" alt="Image" src="https://github.com/user-attachments/assets/4a1f675b-c731-4eba-867c-863a1146fa5c" />


Or even this?

<img width="1003" height="443" alt="Image" src="https://github.com/user-attachments/assets/ff20ea38-8b3e-4963-8edd-25bf2151d5f4" />


Or something else?
