[gtk 3.24] reftests: treeview-crash-too-wide: set a default window size
Fixes the warning:
treeview-crash-too-wide.ui:
(gtk-reftest:1275240): Gtk-CRITICAL **: 16:13:36.264: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar
FAIL
This warning was mentioned in the issue #3746 (closed) (but it doesn't fix the issue, the build still fails here)
This MR adds the lines:
<property name="default-width">512</property>
<property name="default-height">100</property>
inside:
<object class="GtkWindow" id="window1">
The other changes are automatically by glade 3.38.2
