[As yet] unloaded UNC/NAS path doesn't get custom background colour

When I bring up a new lister, and it's using the paths from when it was previously closed, which was a UNC/NAS path, it shows a message about how I need to click to load the content, as expected (and desired.) What doesn't happen is that the custom colour I specified for such paths is not yet applied, and as I use this colour as a signal that it's a network path, I would like that to be the case. Here's a picture of a partial window, where a UNC path is loaded on the right and showing the configured (purplish in my case) colour, but not yet loaded on the left, and thus showing the default black for dark mode.

We've changed that for the next update.

Confirm that this was fixed in 13.15, but with a little twist, which I have reported separately here:
