Re: [csswg-drafts] [css-overflow-4] Unexpected behavior of `continue: discard` on multicolumn containers with spanners (#8721)

Ok, I suppose that makes sense. Furthermore, subsequent columns may overflow in the block direction for real as well, with `column-wrap: wrap`. In fact, overflow may occur in the middle of columns.

```html
<!DOCTYPE html>
<style>
  .mc {
    columns: 3;
    column-fill: auto;
    line-height: 1em;
    height: 2.5em;
    column-height: 5em;
    column-wrap: wrap;
    background: yellow;
  }
</style>
<div class="mc">
1<br>2<br>3<br>4<br>5<br>6<br>7<br>8<br>9<br>10<br>
11<br>12<br>13<br>14<br>15<br>16<br>17<br>18<br>19<br>20<br>
</div>
```

It should render like this:

<img width="455" height="192" alt="Image" src="https://github.com/user-attachments/assets/9de0a08e-7712-4273-9805-6d96488df6a4" />

What should we do if `.mc` has `continue: discard`?
