color palette scrollbar option does not work

Summary:

The color palette at the bottom of the window lacks a proper scrollbar option, because the scrollbar option does not seem to work properly.

When I set the options for Use scrollbar, I get the entire palette in 5.3 rows (see screenshot). It does have a scrollbar, but with the entire palette in view, I don't know why.

What I really want is the palette of old, with 1 row of color chips and a long scrollbar. (I don't remember the last version it was available, but it was a time when there were no other options available for the palette.)(Before 1.4, at least)

Steps to reproduce:

open Inkscape version below
using the button on the far right of the palette where you can choose a different palette, click Configure at the bottom of the menu.
Set the Rows to 1, which enables me to check Use Scrollbar (otherwise it is grayed out)

What happened?

Instead of 1 row of color chips with a scrollbar, I get 5.3 rows (essentially 6 rows). It does have a scrollbar, although it is not needed with the whole palette being displayed.

What should have happened?

I was expecting what the option names imply -- 1 row of color chips with a scrollbar.

Sorry, I was unable to get a screenshot of the Configure options, to show you that I have Use scrollbar checked. (Whenever I open the screenshot program, the Configure box goes away.)

These are the settings:
Tile size = 21, Aspect = 0, Stretch to fill unchecked, Border = 1, Rows = 1, Use scrollbar checked, Enlarge pinned colors unchecked

Thanks for listening!
