Items selected on secondary panel (F3) lose background selection color

[Ark74]

Expected behaviour

Greybird shouldn't lose background color on selected items when using a caja secondary panel (F3 accessed) @ list view.
NOTE: This is only present on list view (Ctrl+2), Icons and Compact seems to work normal.

Actual behavior

When in list view is active selection background is lost when not focused on the other panel.

Steps to reproduce the behaviour

1. Open caja
2. Enable secondary panel (F3)
3. Set list view (Ctrl+2) on secondary panel.
4. Select files or folders on both panels at the same time jumping from one to the other.
5. This affects both dark and light theme, while on the light one is a bit evident something is selected.

Here a small clip,

• Icons View - OK
• Compact view - OK
• List View - X

Using the GTK Inspector we found that using,

.caja-notebook .view:selected:not(:backdrop) {background-color:#6699CC; }

It shows the correct behaviour, but only using the Inspector, it doesn't seem to work when using it on the system recompiling from source.
Any idea is appreciated. 😄

We worked around it with something like this: https://gitlab.trisquel.org/trisquel/package-helpers/-/commit/ae058aaab1a1b922bed6cdd28f41287be002a0f5
