Before a recent update, the color of the line below the buttons was determined by Start Menu -> Configure Menu -> Customize Menu Visual appearance -> Pick Color (with 'use auto color' turned off), now the line below the buttons seems to inherit the color of that taskbar set in Taskbar -> Taskbar blur,transparency, (etc) -> Color (with 'auto color for taskbar' off).

The way the color was set before was not ideal, but I was able to set the color of the line separately from the taskbar at least. Now there is no way to set the line and the taskbar colors separate. If i set the system accent color and use 'auto color for taskbar' then I cannot control the taskbar color.

i.e. if i set the taskbar to dark grey, the line is a lighter grey. I used to be able to set the taskbar to dark grey and whatever the start menu visual appearance color was, that would be the color of the line under the buttons.

Just add a separate control for this please!
