Unintentional Contact with Detached Glove

[bsnalex]

ISF ruleset--

Just wanted to know anyone's thoughts on this. Pitcher's glove for whatever reason ends up on the grass near the pitcher's plate. Throw comes in from right field, misses cutoff and goes close to the glove before F6 finally jumps on it before rolling dead.

Clearly nothing wrong with any of that except for the tantrum that the pitcher threw his glove on the floor. My question is if the ball had hit the glove instead of rolling past-- I can't see a rule for a thrown ball unintentionally contacting detached equipment. Intentional contact is delayed dead ball, three bases from the pitch. Can it be argued that the tantrum was an intentional detaching of the glove therefore the ball is intentionally touched by detached equipment?
