 == Patch Testing Report
 Patch Tested: https://github.com/WordPress/wordpress-develop/pull/11352

 === Environment
 - WordPress: 7.0-beta6-62085-src
 - PHP: 8.3.30
 - Server: nginx/1.29.7
 - Database: MySQL 8.4.8
 - Browser: Brave
 - OS: Ubuntu 24.04
 - Theme: Twenty Twenty-Five 1.4
 - MU Plugins: None
 - Plugins: None

 === Steps Taken
 1. Created a new post using a Verse block with three lines
    separated by Enter.
 2. Published without a custom excerpt.
 3. Checked the generated excerpt via the REST API at
    `/wp-json/wp/v2/posts/6`.
    **Before patch:** Words from adjacent lines were stuck together
    with no spaces. e.g. "this is line onethis is line two"
 4. Created a new post with the same steps after applying PR #11352.
    Checked `/wp-json/wp/v2/posts/9`.
    **After patch:** Words are correctly separated by spaces.
    e.g. "this is line one this is line two this is line three"

 ✅ Patch is solving the problem

 === Expected Result
 When WordPress generates an automatic excerpt from a post using a Verse
 block or Paragraph block with shift+enter line breaks, words from adjacent
 lines should be separated by spaces.

 === Additional Notes
 1. Bug confirmed on WordPress 7.0-beta6. The br tags in Verse
    block content were stripped without preserving word boundaries,
    causing words from adjacent lines to concatenate in the
    generated excerpt.
 2. Removing **`needs-testing`** as patch resolves the issue on
    WordPress 7.0-beta6-62085-src.
