Comment:

 == Test Report
 === Description
 ✅ This report validates that the indicated patch works as expected.

 Patch tested: https://github.com/WordPress/wordpress-develop/pull/8940

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.28
 - Server: nginx/1.29.0
 - Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
 - Browser: Chrome 137.0.0.0
 - OS: Windows 10/11
 - Theme: Twenty Twenty-One 2.5
 - MU Plugins: None activated
 - Plugins:
   * Test Reports 1.2.0

 === Testing Instructions
 1. Add some blocks: Navigation with some elements and Preformatted blocks
 2. Add some background to the blocks to clearly see the limits of the
 block
 3. 🐞 Check the difference between the block editor and the front end. Is
 little but there is some difference

 === Expected Results
 - Line Height should not be different between front and editor.

 === Actual Results
 1.  ✅ Issue resolved with patch.

 === Additional Notes
 - Now with [https://core.trac.wordpress.org/ticket/63549#comment:9
 additional info provided here], I can clearly see the problem that has
 been causing confusion in #60196 (because this also happens to affect
 Lists, but since Lists have an even bigger problem with `data-blocks`
 margins that is like an elephant in the room, this little visual glitch is
 difficult to distinguish in that block.
