"onFinishedAll" callback not firing after calling loadAll()

[frankvw2017]

The 'onFinishedAll' and 'afterLoad' callbacks fire after the final image has loaded by scrolling all images into the viewport, but not after all remaining images have been loaded via the loadAll() public function. Given the names and descriptions of these functions, expected behaviour would be for the callbacks to fire when all images have been loaded regardless of how they have been loaded.
