I want to make it clear im not familiar with coding and therefore cannot contribute code myself, but I noticed that in dropdowns that if one element is selected and the other is hoverd they touch. This is normaly fine but as these have a border radius the common rule is that they should have spacing. I suggest something like a 4px spacing would be sufficent.
If I'm submiting this wrong please inform me as again I'm not familar with this and only noticed this as I use a service that use gpui.
