After the first time the title was placed, we were setting its width, thus forcing get_preferred_width() to return that as the minimum and natural width. To workaround that, explicitly reset the width to -1, -1, causing StLabel->get_preferred_width() to be called, which would give us a meaningful value for minimum and natural width. https://bugzilla.gnome.org/show_bug.cgi?id=688234
