Auto merge of #19789 - ferjm:issue-18831-fb-layout, r=mbrubeck

Do not leave space below baseline when it is not needed (i.e.there is…

… no text)

This is my first layout fix and a naive approach to fix #18831.

- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix #18831
