reproducer to test on Dark Breeze theme

Description of problem:

Shrink the window to its minimum Height, observe multiple GTK errors on standard error:
(TextScrollbarErrors:23242): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar

Follow up to bug 
https://bugzilla.redhat.com/show_bug.cgi?id=1873488
Seems to be fixed through patch

https://gitlab.gnome.org/GNOME/gtk/-/commit/25879ea37e8918a28187dd382e7704051a38f011#bfe7eff23cee77815e1073464071c3f535b7e6f1

But issue is still seen if window is shrinked to minimum height.
logs are filled if error is triggeredd once.


Version-Release number of selected component (if applicable):

RHEL RHEL 9 with GTK3 version:
gtk3-3.24.31-2.el9.x86_64
Dark Breeze theme


How reproducible:
Always

Steps to Reproduce:

1.  g++ -g text_scrollbar_errors.cpp  pkg-config --cflags --libs gtk+-3.0  -o TextScrollbarErrors && GTK_OVERLAY_SCROLLING=0 ./TextScrollbarErrors
2. Shrink the window to minimum height.

Actual results:
(TextScrollbarErrors:23242): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar

Expected results:
No errors
Additional info:

Eclipse uses a custom widget 'Swt-Fixed', I believe in some cases widgets are created "very small" and then they are expanded to window size or comparable size. Though its not uncommon to have a view that has the same height as the the scrollbar slider, at least for our theme (since the minimum scrollbar slider height is about 3 rows of text, reducing the height of a view with a text editor to about 5 rows of text already causes the issue).
