OS#14915011: Force deferred parsing off under F12 console eval. We used to disable deferral and redeferral of console eval expressions based on their length. Short scripts now allow redeferral, which requires creation of scope info, which in turn doesn't work under console eval. Simply forcing deferral off in this scenario.
