Site Editor: View on the editor back end doesn't match the front-end

[franzaurus]

Description

In WordPress 6.3-beta3, the template view at the back-end, doesn't match the front-end view. I noticed that at the front-end, bulleted list blocks are automatically inserted in the query block for blog posts, and in the navigation page list as well. It seems padding values are being ignored too.

Step-by-step reproduction instructions

1. Activate Twenty twenty-three theme
2. Open Editor
3. Observe the home template content are displayed properly
4. View the front-end
5. Observe the front-end view doesn't match the back-end view

Hey @franzaurus - I haven't been able to recreate this with a fresh installation of WordPress (apart from the beta tester plugin). Are you able to recreate it in any other environments?

I also notice that you've got some additional content in your site. I don't expect that would make a difference - but are you able to check again with a totally empty/default installation of WordPress?

Hi @jordesign, thanks so much for your help in testing the issue. For this test, I used a WordPress fresh install in Localwp instance. But since your report said you can't replicate the issue, I've setup a different test environment via instawp. Apparently the issue is not reproducible there.

So I guess this back-end/front-end mismatch view is specific to a certain environment. In this case the issue is introduced by Localwp environment. I added a video in the original post for clarity.

Instawp environment

• PHP: 8.1.20
• Server: Apache/2.4.57 (Ubuntu) mod_fcgid/2.3.9 OpenSSL/1.1.1f

• Browser: Firefox 115.0 (Windows 10/11)
• Theme: Twenty Twenty-Three 1.1
• MU-Plugins: None activated

Hi @franzaurus,

This issue was also reported in #52199, but it is probably specific to the Windows OS environment.

Here is the ticket for the core: https://core.trac.wordpress.org/ticket/58711

This problem has also been fixed in Changeset 56136. Therefore, the fix will be reflected in the nightly build or the next beta version.

I would like to close this issue, but if I have missed something, please comment.
