In the `campsite_cherry_grove_3` abandoned camp structure, one cherry tree can never be placed successfully

Cherry placement requires a space check: the second-layer 5×5 area above must consist solely of blocks tagged #minecraft:replaceable_by_trees. However, a Cobweb exists in that area, and Cobweb is not part of this tag or its sub-tags

Call chain:

cherry.json //(data\minecraft\worldgen\template_pool\abandoned_camp\trees\cherry.json)
    → cherry_checked.json
      → feature: "minecraft:cherry"
        → cherry.json //(data\minecraft\worldgen\feature\cherry.json)
          → "type": "minecraft:tree" //(TreeFeature.place())
            → TreeFeature.getMaxFreeTreeHeight() //Scans each layer with radius from getSizeAtHeight(), upper_size=2 yields a 5×5 area per layer
              → minimum_size: minecraft:two_layers_feature_size //(TwoLayersFeatureSize)
                   config from cherry.json: limit=1 (default), lower_size=0 (default), upper_size=2
              → trunk_placer: minecraft:cherry_trunk_placer //(CherryTrunkPlacer.isFree())
                → TreeFeature.validTreePos()
                  → state.isAir() || state.is(BlockTags.REPLACEABLE_BY_TREES) //This is where it checks whether the block is air or tagged #minecraft:replaceable_by_trees
