This already does rewind on creating from class, and calling next() once - so it should be on the latest line already:

$this->logIteratorFactory->getLogIterator($this->settingsService->getShownLevels());
	...
	new LogIterator($handle, $dateFormat, $timezone);
		...
		__construct($handle, string $dateFormat, string $timezone) {
			...
			$this->rewind();
				...
				$this->next();

What does it fix? I remember investigating something with it, but didn't finish. But not sure that current code brings something to it

Before the fix I always got null has return from getLastItem

There is something weird going on because I agree with @Antreesy the code is supposed to return a rewinded iterator already from the factory
