@Madhu kumar Thank you for reviewing the issue! I have removed credit from you on this issue because the screenshots doesn't show the problem. Also, two other reviewers have already submitted screenshots on the issue, meaning that posting more screenshots isn't helpful.

Committed 0daba4e and pushed to 9.3.x and 9.2.x. Thanks!

As far as I can tell the wrong patch was committed here. At least https://git.drupalcode.org/project/drupal/commit/0daba4e doesn't match https://www.drupal.org/files/issues/2021-05-15/3214140-2.patch

Sorry for the noise in case I'm missing something and this is in fact correct.

Applied patch successfully. Attached screenshot
Thanks

OK, re-opening then to increase visibility. Not sure if this has been committed/pushed in the meantime, but I don't think so.

Thank you @tstoeckler! Reverted and committed again.
