AirBoundary not considered transparent by 'Annual Daylight'?

In this example there are two rooms, one with windows and the other without, I followed this post below and researched and found that when performing a simulation ‘Daylight Factor’ the air boundary is completely translucent, but when simulating ‘Annual Daylight’ the air is conveniently completely non-translucent?

Whether ‘Annual Daylight’ and ‘Daylight Factor’ simulations are different for air boundaries?
Looking forward to your reply, thanks!

This looks like a bug! I know that @mikkel is working on a solution.
