Here, the result at Factor 1 looks correct, will confirm though since at Factor 0.0, I would assume the result to not be affected by Bent Normals at all?
Or it this a known limitation, @fclem?

This is how is has always worked. At this point I would just avoid more regression. But this could be fixed in EEVEE's rewritte.
