A user on the AnswerHub pointed out that his reflections when using a Movable Skylight with Distance Field Ambient Occlusion produces black results when combined with a reflective material.

I traced this issue all the way back to 4.9.2, and it exists there as well. I spoke with Tim Hobson and we came to the conclusion that entering a bug would be the safer choice, as I am unsure whether or not this is a limitation, a bug, or expected.

Note I can reduce the severity of this issue by modifying the Min Occlusion and Max Occlusion Distance values on the Skylight, which I can pass on to the user.

Steps to Reproduce

Download and Open attached project.
