Thank you for the feedback!

Be aware that the "scrollbar size" setting currently configures the scrollbar width, not the scrollbar height. By default, with the "small" size, scrollbars should continue to be 7px wide, as was the case with the default app styles before v3.2 (see main.scss in v3.1, noteStyle.ts in v3.1).

Screenshots: Comparing the editor and viewer scrollbar width

To double-check that the scrollbars are the same width (at least on my Linux computer), I stacked screenshots of the scrollbar in the viewer above a screenshot of the scrollbar in the editor:

I talk about the width. If you compare my screenshots, the viewer width is too small and in dark mode it's not really visible

Note: The note viewer scrollbar has a different border-radius from the main app scrollbars, possibly causing a slightly smaller width for very short scrollbars. In addition to the contrast issues, this should be resolved by #11708.
