GtkInfoBar: 1px of background color is still visible when not :revealed
There are several issues with GtkInfoBar's "revealed" property:
- Even with "revealed" set to false, a 1px high blue bar is visible. To reproduce this, open the Info Bar demo and use the inspector to set revealed to false.
- gtk_info_bar_{get,set}_revealed don't show up in the docs
- wrong type: https://gitlab.gnome.org/GNOME/gtk/blob/gtk-3-22/gtk/gtkinfobar.c#L1249
Gtk is 3.22.30, theme is Adwaita
