Thunderbird under Plasma 5 has no scrollbar arrows [solved]

Here's another annoyance from GTK land.

I'm running mail-client/thunderbird-52.3.0 in a Plasma 5 environment (kde-plasma/plasma-meta-5.10.5) and the scrollbars have no arrows on them. I guess it's just another manifestation of insanity among those GTK developers; I give thanks that the KDE people aren't that crazy. Qt windows have normal scrollbars; I wish that Thunderbird did. I have thousands of emails, so I need much finer scrolling than I can get by trying to drag the slider by impossibly tiny increments. Also, I like to look at the Subject lines without changing the message-read status, so scrolling with the arrow keys doesn't work out for me either.

I tried some tweaks I read about on the internet, but they were all pretty much directed to changing the behavior in a Gnome or XFCE. I haven't seen anyone address this for KDE (any version). Yes, I have System Settings -> Window Management -> KWin Scripts -> Enforces Window Decorations on GTK+ window enabled, and yes I set up ~/.config/gtk-3.0/gtk.css as

Create or add to ~/.config/gtk-3.0/gtk.css

*{

-GtkScrollbar-has-backward-stepper: 1;
-GtkScrollbar-has-forward-stepper: 1;

}

Cheers,

That's great. I replaced ".scrollbar" with an asterisk in my ~/.config/gtk-3.0/gtk.css file and it worked. I've got arrows on the scrollbar now. Thank you.
