When running parcel without scope hoisting,
globalreferences are not passed through correctly in theDevPackagermodule. This results in runtime errors when any code directly usesglobal.without any checks of its existence sincevar global = arguments[3]is always undefined. These changes amend the pass through of the global object, so thatarguments[3]exists under a privately namespaced variable to prevent collisions with other constants named global.🚨 Test instructions
