Issue while setting scrollbar track color

[klonuo]

Hi,

if I set theme setting "scrollbar_track_fg": [255, 0, 0], it has no effect.

According Devin:

In src/view/ui/split_rendering.rs, the scrollbar track colors are hardcoded based on whether the split is active split_rendering.rs:849-859 :

- Active split: Color::DarkGray
- Inactive split: Color::Black

This code completely ignores the theme.scrollbar_track_fg value you set.

If so please allow setting the color for scrollbar tracker.
