Re: [csswg-drafts] [css-text][text-spacing] Visual regressions of line-start at portals and news sites (#9511)

> A new critical regression case for `space-first` was reported ([source](https://xtech.nikkei.com/atcl/nxt/news/18/16172/).) Updating the [table](https://github.com/w3c/csswg-drafts/issues/9511#issuecomment-1774991353).

Here is the html code:

```html
<p>
(1)量販価格帯の新たなEVシリーズを2027年以降、北米を皮切りに投入予定<br>
(2)コンパクトスポーツ多目的車(SUV)を含む、グローバルで人気の高いセグメントに向けたEVシリーズ<br>
(3)両社で世界規模での生産を可能にする設計を検討<br>
(4)次世代バッテリーに関する協業の深化についても検討
</p>
```

In my [`space-first` proposal](https://github.com/w3c/csswg-drafts/issues/2462), each line after `<br>` must be treated as a first line that "space-first" is applied.

Now I found that the definition of `space-first` was changed between 2022-12-31 and 2023-03-01: 

- https://www.w3.org/TR/2022/WD-css-text-4-20221231/#valdef-text-spacing-space-first

  > Behaves as space-start on the first line the block container and each line after a forced line break but as trim-start on all other lines.

- https://www.w3.org/TR/2023/WD-css-text-4-20230301/#valdef-text-spacing-trim-space-first

  > Set fullwidth opening punctuation with full-width glyphs (spaced) on the first line the block container. Otherwise as trim-auto (unless allow-end is also specified).

I believe this is a mistake.
