The tab border stuff was apparently removed in gtk+ 3:

Not easily, as far as I'm aware, but you could probably rig something up
with Inline::C or FFI.  But nowadays, with Glib::Object::Introspection,
if some function is not callable, then there's probably a significant
obstacle, like the presence of varargs or untyped pointers in the
signature, which would not be easily overcome with Inline::C or FFI.
