pointSize styling doesn't work for gltf using EXT_mesh_features and EXT_structural_metadata

tileset.style = new Cesium.Cesium3DTileStyle({
show: true,

This is not an issue of the 3D Tiles format itself, but rather of CesiumJS. Closing in favor of CesiumGS/cesium#12398 (and I'll post additional details there)
