Have some container widgets changed, or lost, some default
spacing/padding/margins too? For instance, it looks like GtkActionBar
used to have some hard-coded spacing between its child widgets (added
via gtk_action_bar_pack_start()), but not with gtk4.
Based on some commits I remember seeing, I think the new policy is that widgets should not enforce such properties. Which, IMO, is a good thing, though again potentially a pain for porting.
