Steps to reproduce

1. start Sublime Text in safe mode, the color scheme set is Mariana (not light)
2. run view.add_regions("foo", [sublime.Region(0, 0)], annotations=["<div>bar</div>" * 30])
3. hover the annotation

Expected behavior

A dark scrollbar

Actual behavior

A light scrollbar

Environment

It looks like the luminosity attribute is hardcoded, it's file_light regardless of the color scheme.

I upgraded Windows from 1803 (2018) to 20H2, and it was fixed.

Actually it wasn't.
