Reminiscent of
Ephesians 6:4
And you, fathers, provoke not your children to anger: but bring them up in the discipline and correction of the Lord.
St. Thomas's commentary
When he says And you, fathers, provoke not your children to anger, it is not that the fathers must give in to their will in all matters. Here it must be noted that the authority of a father with respect to his child is different from that of a master with respect to his servant. For the master employs his servant to his own advantage, but the father manages his child for the childβs advantage. It is necessary that fathers educate their children for the childrenβs own good; not, however, by excessively restricting or subjecting them.
and
Colossians 3:21
Fathers, provoke not your children to indignation, lest they be discouraged.
St. Thomas's commentary on Colossians for this verse is similar to his Ephesians one above.

CCC 2286-7 is referring to unintuitive extensions of scandal. A teacher who prevents her students from learning would be causing scandal by indirectly leading them to do future evil through ignorance. A teacher who angers her students is both preventing them from learning, and is undermining their trust in legitimate authorities (i.e. teachers). I think this is the sort of thing the Catechism has in mind. The simpler interpretation that provoking someone to sinful anger is a form of scandal makes sense but has nothing specifically to do with teachers, and so I think it is more than this.
