Scrollbar overlaps history list when overlay scrollbars are turned off

[cassidyjames]

Describe the bug

When I disable overlay scrollbars in GNOME Settings (or when a distribution such as Endless OS sets it by default), the non-overlaid scrollbars overlap and obscure the history list of colors.

To Reproduce
Steps to reproduce the behavior:

1. Disable overlay scrollbars in GNOME Settings, or use Endless OS where they're off by default
2. Pick a bunch of colors so your color history is sufficiently-long (10+ colors)
3. Make sure your window is not too tall (to make sure the colors overflow the container and trigger a scrollbar)
4. See the obscuring scrollbar :)

Expected behavior

I would expect the window size or layout to adjust to accommodate the non-overlaid scrollbar

I would have expected that too, but apparently not.

Unfortunately, I don't know of any way to prevent this/move the scrollbar next to it.
