You could do
#timeline-band-scrollbar-0 .timeline-band-scrollbar-thumb {
...
}
to target your CSS at the thumb.

There's a technical challenge to do that. The band redraws itself only
occasionally, when you've scrolled to a point where you're about to go
beyond the time span that it has painted. This time span is some
multiples of the visible width of the time line. The band only knows the
overall amount of space the events take up in that time span. It doesn't
know how much space (vertically) the events take up at any particular
point in time. So, it can't render its scrollbar at that level of
granularity.
