The toolbar doesn't close automatically when the sidebar is opened in vertical mode and focus mode is on. To reproduce, open the sidebar in vertical mode, enable focus mode, and visit a website like Amazon or YouTube. The toolbar remains open unless the sidebar is closed, and this behavior is inconsistent (may close sometimes).
The toolbar should automatically close and open independently of the fact that the vertical sidebar is opened or closed.
