Gtk.Window.set_skip_taskbar_hint seems to be broken
The following problem is the same in Python 2.7.18 and 3.9.7. OS is Solus Linux 4.3 Fortitude with Budgie, GNOME version is 40.4.0, PyGObject is 3.40.0, Terminator is 2.1.1.
I've been using Terminator for more that a year now and since yesterday - after playing around with its config file - its hide_from_taskbar flag doesn't work anymore, the application icon is shown in the task list regardless of the setting. I was able to trace this (lack of) behavior back to the place in the code where Terminator calls Gtk.Window.set_skip_taskbar_hint(value), and whatever value I provide, the result is the same, the application icon doesn't go away. It looks like I'm not the only one with this problem, see https://github.com/gnome-terminator/terminator/issues/475. As is mentioned there, the Terminator code that handles hide_from_taskbar hasn't been changed for years. Next, I'm gonna try and write a minimal program that shows this behavior. I'll post a link here.
