Highlighting of Select Row when Switching Pane in Nemo

[ChrisOfBristol]

Problem as posted on GitHub for Nemo:
4.2.3
Nemo window
Ubuntu Budgie 19.10
? Nvidia 340.107
64

The selection and highlighting of a row isn’t what I would expect.
If I hover over a row in paneA it is highlighted slightly, if I then click it, it shows that it is selected by being highlighted strongly and I can now do things to that row. For example if I click and hold, I can drag and drop it.

If I then move the pointer to paneB, I can do the same, and the same happens, but sensibly the row in paneA also stays highlighted strongly - to me this indicates that it will still be selected if the pointer returns to that pane.

However, If I now go back to the row in paneA, although it is still highlighted, I can’t move it after click and hold. Presumably because it is no longer selected despite being strongly highlighted.

This is inconsistent.

I would prefer it to have stayed selected for that pane, so one row is highlighted in each pane.

If that were thought to be confusing, and it was decided that only one row in total could be highlighted in the Nemo window, I think that when I switch to the other pane, it should lose its highlighting to show that it is no longer selected.

Answer from Github for Nemo:
...this generic over-ride css in ~/.config/gtk-3.0/gtk.css. If you don't have this file create a empty one. It should in theory be theme agnostic, but results may vary depending on system theme.

.nemo-window .nemo-inactive-pane .view,
.nemo-window .nemo-inactive-pane iconview,
.nemo-window .nemo-inactive-pane .view:selected,
.nemo-window .nemo-inactive-pane iconview:selected {
background-color: shade(@theme_bg_color, 1.05);
color: @theme_fg_color;
}

shutdown nemo with the command nemo -q and reopen nemo.

What version of Arc are you using? I can't reproduce the problem with the Arc Deb installer for 19.10 with Nemo 4.4.2. Arc is one of the themes that doesn't need that gtk override css.

I can't work out how to check what theme I am using (apart from switching to one in Budgie Themes), let alone which version.
