Thank you very much for your time Kevin!
And you are absolutely right (I had no idea you would look at the code... so much appreciated!)
I switched back to the Clearlooks enigine, and the darn thing finally showed up! I am scratching the work I did this past week or so with the pixmap engine, and I will update the existed themes so they look good in Gimp 2.10.1x (actually I've started already doing that).
So, the image they show on the GtkNotebook docs page, showing that hint-stripe, is most probably using the Clearlooks engine (it was the Gnome preferred engine, before they switch to Adwaita I think) .
Once again, thank you very much!
