In general, errors that occur during font locking are swallowed, on purpose. Font lock is pretty much an invisible, background genie that does its thing whenever it feels like it, independently of what else you might think is going on. It would generally be inappropriate for such an error to be raised, so font lock just gives up at that point, instead of raising it.
