     since focus change of the dialog's focussed widget (text)
     somehow currently chooses to destroy
     a pre-existing (read: foreign, user-initiated) X11 primary selection
     (via gtk_label_select_region() -> ...
     -> gtk_clipboard_set_contents()/gtk_clipboard_clear()),
     we need to ensure
     that the widget does have its gtk-label-select-on-focus property off,
     in order to avoid having the label become selected automatically
     and thereby having pre-existing clipboard content nullified.
     Side note: this selection issue only applies to widgets
     which have both
                  <property name="can_focus">True</property>
                  <property name="selectable">True</property>
