Presumably another LFC/legacy layout difference, Alan?
Comment 3 zalan 2021-09-16 06:20:01 PDT 
It looks like a mismatch in text width vs. available horizontal space where IFC manages to fit the content on the line while legacy does not. Visually the IFC layout looks correct as the content does not look to be overflowing the containing block. I also can't reproduce it on trunk.
Comment 4 Tim Guan-tin Chien [:timdream] 2021-09-16 18:38:14 PDT 
It is only reproducible with a specific window size.
