Struct ScrollbarState 

pub struct ScrollbarState { /* private fields */ }

Where in the thumb a drag was grabbed.

Shaped like gpui’s ScrollHandle — an Rc cell the view holds one field of and the bar clones — for the same reason: both mutate through &self, so the bar carries its whole gesture without the view wiring a single listener. Without it the thumb would jump its middle to the pointer on every press.
