There is a problem with drillPickFromRayMostDetailed

[DoubleYellowEgg]

What happened?

When I load a 3dtileset using a new PrimitiveCollection, I can't pick the coordinates on the 3dtileset using drillPickFromRayMostDetailed. However, when I load the 3dtileset directly using the viewer.scene.primitives.add() method, I can pick the coordinates.

The following method fails to pick the coordinates.

const collection = new Cesium.PrimitiveCollection();
scene.primitives.add(collection);  // Add collection
const tileset = await Cesium.Cesium3DTileset.fromUrl(
   "http://localhost:8002/tilesets/Seattle/tileset.json"
);
 collection .add(tileset);

scene.drillPickFromRayMostDetailed(ray)  => no Cesium3dtileset

Adding the 3dtileset directly using viewer.scene.primitives.add works.

const tileset = await Cesium.Cesium3DTileset.fromUrl(
   "http://localhost:8002/tilesets/Seattle/tileset.json"
);
scene.primitives.add(tileset );

scene.drillPickFromRayMostDetailed(ray)  => yes Cesium3dtileset

There are some functions on the API level. And under the surface, it can quickly become hard to track what these functions are actually doing. But based on the (short) description here, I'll go out on a limb (and would be willing to bet) that this has the same root cause as what was addressed in #13097

(Maybe you or whoever is 'triaging' this issue wants to give it a try, with the branch from that PR, and see whether that PR could resolve this issue here as well...)
