Strange rendering of 3D Tiles

[levelost]

Good day. I can't figure out what to do with these tiles. The dataset is quite old and displays correctly in older versions of Cesium. In deck.gl some tiles are only displayed at far zoom levels and at certain angles. I suspect that there is an incorrect interpretation of the viewport. But I don't know what to do about it.

Root tile:

{
  "asset": {
    "version": "0.0",
    "tilesetVersion": "1.0"
  },
  "geometricError": 1769472,
  "root": {
    "boundingVolume": {
      "region": [-3.14159265358979, -1.5707963267949, 3.14159265358979, 1.5707963267949, -5, 4674]
    },
    "geometricError": 1769472,
    "refine": "REPLACE",
    "children": [
      {
        "boundingVolume": {
          "region": [-3.14159265358979, -1.5707963267949, 0, 1.5707963267949, -5, 2231]
        },
        "geometricError": 1179648,
        "refine": "REPLACE",
        "content": {
          "uri": "/3dtiles/tilesets/tileset_0/20251223_2/0/tileset_0-0-0.json"
        }
      },
      {
        "boundingVolume": {
          "region": [0, -1.5707963267949, 3.14159265358979, 1.5707963267949, -5, 4674]
        },
        "geometricError": 1179648,
        "refine": "REPLACE",
        "content": {
          "uri": "/3dtiles/tilesets/tileset_0/20260120_67/1/tileset_0-1-0.json"
        }
      }
    ]
  }
}

Layer creation (deck.gl 9.2.5):

const tiles3d = new Tile3DLayer({
    id: '3dTiles',
    data: '<url>'
})

Very similar to this case:
visgl/loaders.gl#1994

Children have transformation matrices.
"transform": [1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, -283436.202314219, -133866.236217565, 140937.674060337, 1]
