Vertical separator of left sidebar is misaligned with vertical separator of window decoration

[Amr Ibrahim]

To reproduce:

1. Open gnome-control-center (latest 1:3.25.92.1-0ubuntu1)
2. Look at the vertical separator of the sidebar; between the categories and settings; it is misaligned with the vertical separator above it in the window decoration
3. Select Dock; the sidebar separator becomes darker and it is still misaligned

It also happens in gnome-tweak-tool.

This bug does not happen in Adwaita.

See the attached screenshots.

Also in gnome-tweak-tool, not only g-c-c.

Looks like this is probably triggered by the Ambiance theme's custom titlebar padding. Although you could argue the real bug is then in Gnome itself for placing the titlebar separator in the wrong location for the current theme.
