By setting a sort function on the @box, one can dynamically
reorder the children of the box, based on the contents of
the children.
The @sort_func will be called for each child after the call,
and will continue to be called each time a child changes (via
[method@Gtk.FlowBoxChild.changed]) and when
[method@Gtk.FlowBox.invalidate_sort] is called.
Note that using a sort function is incompatible with using a model
(see [method@Gtk.FlowBox.bind_model]).
