Problem/Motivation
In testing #2959493-151: Allow Layout Builder live previews to be toggled to allow easier drag-and-drop, I discovered that the search block form is a little odd-looking when looking at it in Layout Builder's placeholder ("grid") mode. One of these things is not like the others:

The problem is that Classy, Bartik, and Umami all have a template for this block, and each of them adds the container-inline CSS class, which displays the form inline and thus negates the text centering that Layout Builder adds to the placeholders.
Proposed resolution
TBD
Remaining tasks
TBD
User interface changes
TBD
API changes
I kindly doubt it.
Data model changes
Doubtful.

quietone commentedI tested this on a fresh install of standard and umami. I was not able to reproduce the problem.
Therefore, closing as cannot reproduce. If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue (starting from "Install Drupal core").
Thanks!
