Problem/Motivation
I was testing the installation today and I still see the "Malformed HTML string" that I though we fixed in a patch before: 
            
              https://www.drupal.org/project/wxt/issues/3377588
              
              💬
              [D10] - Disallowed or malformed HTML in a translation string.
                Fixed
              
            
Steps to reproduce
Install latest 5.4.0 or 5.4.x-dev, you'll see the warning at the end of the installation
Proposed resolution
- It seems like that issue was already addressed in a bootstrap issue: 
            
              https://www.drupal.org/project/bootstrap/issues/3249470
              
              📌
              Error generated when importing translation
                Closed: won't fix

Remaining tasks
I believe the patch is still listed in the wxt's composer.json file
"patches": {
            "drupal/block_content_permissions": {
                "2920739 - Allow accessing the 'Custom block library' page without 'Administer blocks' permission":
                "https://www.drupal.org/files/issues/2022-07-26/2920739-55.access_listing_page.patch"
            },
            "drupal/bootstrap": {
                "3249470 - Error generated when importing translation":
                "https://www.drupal.org/files/issues/2021-11-17/3249470-3.patch"
},
So the patch is not applied for some reason? I know it's not a big issue, but I'm intrigued about this.
