    pathbar: Avoid excessive minimum label width
    
    We set a minimum width in characters for the labels in the pathbar not
    to collapse into a single ellipsis. Labels under this threshold are
    excluded because in that case we just set them not to ellipsize and let
    GtkLabel take care of the sizing.
    
    However, the width in characters metric fails for variable-width fonts,
    such that in some cases we still set a wider label width than what the
    label text occupies.
    
    So, raise the ellipsizing threshold further, and do it proportionally.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/-/issues/2202
