Keyboard focus not visible on popover menu entries

[Egmont Koblinger]

Open a popover menu with text entries, such as:

- Files (Nautilus): "hamburger" menu on the upper right

- Tilix: "hamburger" menu, or right-click over the terminal area, or Profiles -> a triangle in the left-hand sidebar

Use the keyboard (Tab, or Up and Down) to navigate in the entries.

When an icon entry (wherever present) is focused, it has a thin orange border. But when simple text (or checkbox, radiobutton) entries are focused, there is no visual feedback at all, you can't see which item is selected and hence which item would be activated by Enter or Space.

This makes popovers pretty unusable via the keyboard.

Does not happen with Adwaita.
