Suspicious code in Lambertian prefiltering compute

https://github.com/stride3d/stride/blob/5f3542d08b701b90a5b1544e01e42a4d628b2105/sources/engine/Stride.Rendering/Rendering/ComputeEffect/LambertianPrefiltering/LambertianPrefilteringSH.cs#L104

Been reading the code to get to really know those light probes, when I stumbled on something that doesn't seem right. Looks like the order's switched, was it intended to assign groupSizeX instead before trying to decrease it?

                var groupCountX = 1;
                var groupCountY = sumsToPerfomRemaining;
                while (groupCountX >= short.MaxValue)
                {
                    groupCountX <<= 1;
                    groupCountY >>= 1;
                }

Start in sources/engine/Stride.Rendering/Rendering/ComputeEffect/LambertianPrefiltering/LambertianPrefilteringSH.cs around line 104 and trace the group-count calculation surrounding the reported loop. Confirm whether the condition and update order are intentional, then validate the affected rendering or compute behavior; done means the suspicious logic is resolved and the result is verified.
