Short description of error

The "Reflection Cubemap" light probes do not properly reflect metallic objects. The objects that are metallic only appear to be shadeless and black in the reflections.

Exact steps for others to reproduce the error

From file:

Open Blender 2.8.
Open the provided file.
Observe the objects with light probes around them.
You should notice that the reflected metallic objects appear to be black and shadeless.

From scratch:

Open Blender 2.8.
Add a cube to the center of the grid.
Move the cube 5 Blender units on the Y-axis.
Select the default.
Split the view and open a node editor.
In the node editor select "Use Nodes."
On the metallic shader turn the "Metallic" slider to 1.
On the metallic shader turn the "Roughness" slider to 0.
Select the second cube and assign the same material that you just created.
Add a "Reflection Cubemap" to the center of the grid.
Go to the light probe properties and change the clipping start to 1.001.
Change the influence to "Box."
Go to the side of the default cube that is facing the second box and observe how it reflects the second metallic cube.
The second metallic cube should appear to be shadeless and black.
