Ladders are not visible when looking at them through clouds

I built a tower up to the vertical build limit and put ladders along one side. When looking through the clouds at the ladders, they were invisible or were not rendered. I expected to be able to see the ladders through the cloud/fog effects as I see all other blocks. In the screen shots there are ladders all the way to the top of the tower but they are not rendered in the clouds. Fancy graphics was on.
