I use the proportional Go font in Bike 1.17.2 (165). Inserting an emoji makes the line containing it taller:
It doesn’t happen with the “System” font:
This is probably just an issue with my font, but I thought I’d post it just in case it’s actually a bug in Bike.
I’m not sure, but I think it’s working as intended. For example I see the same behavior in TextEdit when I insert an Emoji while using the Monaco font.
In Bike I have no special handling for emoji layout, I’m just using the line heights that core text returns to me.
With that said I do think it makes the lines look a bit ugly in these cases, but that’s why I use default font
