kMirror with reflection probes issue

[dikafe]

I am trying to make a floor reflective using the kMirror method for the floor object itself. I would like the walls, which are planar objects (no volume) to be affected by reflection probes. I am not sure if there is a contradiction per design, but when a kMirror object is added, a reflection probe placed in the same scene does not render the front face of the planar objects, i.e. of a plane GO. I figured that if the material on the planar object is set to render the back face (or both) the reflection probe render is fine. Any suggestions on this odd behaviour? As a note, if the kMirror component is disabled then the reflection probe bakes everything as expected.
