Since 2.335 the vertical alignment of the build status icon is not correctly anymore.
Bad vertical icon alignment for M and S icon sizes
Seems that this is again broken in 2.348
Now the vertical alignment is broken.
Tested locally with core-pr-tester. Looks ok, but the icons is closer to the text than before (but on the same vertical line). So it fixes the problem to me, but could be improve to have some space between the icon and the text.
Git bisect pointed me to https://github.com/jenkinsci/jenkins/commit/627912239e6c0e4324002d1bfd45e241b34127b3 which was introduced by JENKINS-67515.
