I have just tried that with both the F1 and F2 variants (German OOB since you did not specify another one) in a test scenario in summer, winter and desert just in case the icon number affects things.
All spun to face the target on firing, so I don't see the problem here?
It would not be obvious in all cases when using that unit which explains why it's been missed for the Summer version of the 48/F1 icon since March..and the problem also affects 8 other units and will require a code change to correct
