Staircase-shape in sentinel3 results.

This looks like this issue: #1072 (comment)

Normally the solution is to enable this option:

datacube._pg.arguments["featureflags"] = {
   "use_new_feature_extent_intersection": False,
}

But in this case, it only adds 3 lines of pixels:

Minimal graph to reproduce the issue:

{
  "process_graph": {
    "loadcollection1": {
      "arguments": {
        "bands": ["Syn_Oa08_reflectance"],
        "id": "SENTINEL3_SYN_L2_SYN",
        "spatial_extent": {
          "east": -1.1,
          "north": 43.1,
          "south": 40.1,
          "west": -5.1
        },
        "temporal_extent": ["2026-06-01T10:30:36Z", "2026-06-01T10:30:37Z"]
      },
      "process_id": "load_collection",
      "result": true
    }
  }
}

The staircase effect changes when the spatial extent changes. This could be due to faulty intersection at the edge of a product. In the past this happened due to faulty bounding boxes in the source collection
