I think http://bugzilla.gnome.org/show_bug.cgi?id=63480  is tracking the status of 
this.

Probably yes, judging from the mentioned bugzilla entry.

This seems to be handled in  gtk_widget_child_focus, which gets called to 
move the focus between
the containers children. From the docs:

 * This function replaces gtk_container_focus() from GTK+ 1.2.  It was
 * necessary to check that the child was visible, sensitive, and
 * focusable before calling
 * gtk_container_focus(). gtk_widget_child_focus() returns %FALSE if
 * the widget is not currently in a focusable state, so there's no
 * need for those checks.
