Grayed-out progress bars in sidepane [$50]

[Giulio Sant]

After the latest gtk update, I've noticed the following visual glitch. There are cases in which it's as if the sidepane in Files lost focus and the progress bars of the mounted volumes appear grayed out. This can be reproduced by clicking on an empty area in the file manager. The normal appearance (blue bars) is restored as soon as I hover the mouse pointer over the sidepane.

Marking as "incomplete" in the stylesheet. I can't seem to affect it from .progressbar or anything like that. Not sure how it's getting its colors. Most likely something to do with the :focus:selected change

@Daniel Fore if you use any other theme (that is not based on elementary theme of course) you' will not have this issue. So yeah it's a CSS issue.

@bil Except that's not the problem. The problem is that the code is trying to get the :selected style alone. While this would work in previous versions of the stylesheet (and may work for other stylsheets), it won't work anymore because we now distinguish between :selected and :selected:focus. This is an a11y feature.

Changing lines 53-62 of gtk-widgets.css with the following fixed it on my end, and i haven't noticed any side-effects

*:selected,
*:selected:focus {
    background-color: @theme_selected_bg_color;
    color: @theme_selected_fg_color;
}

@phillip As I explained above, this is not a proper solution. Distinguishing between :selected and :selected:focus is an *accessibility feature* and will not be changed.
