As a man of the cloth - I say as long as she is just being an idiot - let her. The less reaction she is given, the less she will get out of the efforts to disrupt - and she will tire of the game - or she will escalate her disturbances, giving the church reason to bar her from attending. She has to cross that line - and so far, she hasn't. The priest also may wish to take it up privately with her if he feels her current actions are too disruptive to be allowed, but not enough to bar her.

Because its a mass, the level of structure is a bit... cast in stone. Were it a protestant church, you would get a different reaction to be sure. I have seen this in a protestant church - to where the pastor organized a rather ... cruel response. During songs, early in the final chorus was cut out at specified times by everyone - except the disruptive person - who was caught singing in key and oblivious - to which everyone started pointing and laughing at them. About three songs into it, the person got pissed, stormed out, and from what I understand, never returned to that church.
