HGCal RecHit position (hexagons) not aligned with center of the cell #128

In a phase2 workflow, if I had a HGCAL LayerCluster collection (hgcalMergeLayerCluster in the attached image), using the Calo Cluster purpose, the rechits of the clusters are rendered as hexagons, but their location is not aligned with the blue crosses that represent the position of the center of the seed cells. The hexagons in the image are rounded by the red circle, while the crossed by a blue circle.
I'm using a Phase2 reconstruction geometry (D110) dumped directly using the standard utility via the command line:

cmsRun $CMSSW_RELEASE_BASE/src/Fireworks/Geometry/python/dumpRecoGeometry_cfg.py tag=Run4 version=D110

I'm using a local build of cmsShowWeb using CMSSW_16_0_ROOT636_X_2025-10-28-1100 with the HEAD of this repository.

I have verified that the coordinates of the centers are, indeed, inside the 6 corners of the cells.
