Gtk3: css decoration doesn't apply when window is maximized
Current behavior
Applying background-color
on decoration
doesn't apply when the window is maximized.
Here is a screenshot when the window is not maximized:
And when it's maximized. We cannot see it but instead of white it's transparent and we see behind the decoration.
Expected outcome
Background-color applying whether the application is maximized or not.
Version information
Ubuntu 21.04 (Hirsute Hippo) with GTK3 3.24.25-1ubuntu4.1 on X11.
