Mesh raycast function problem

[cnywt]

Describe the bug

When the BufferAttribute class uses the normalized attribute and is set to true; the raycast function of the Mesh class does not use the normalized Vector3 calculation synchronously
Describe the bug

To Reproduce
1、create a BufferGeometry width position attribute data not normailized
2、position BufferAttribute normalized attribute set to true;
3、render this geometry to scene and get it by Raycaster

Do you mind to properly fill out the issue template? Also please demonstrate the issue with a live example.

Sorry, my English is so bad; so I hope to describe the problem briefly and directly;
This problem was encountered by me helping a stranger solve the inaccurate location of the gltf model by clicking on it, so I don't have an online demo for the time being;

Please let me know if the issue has no value and I will close it;

create a BufferGeometry width position attribute data not normailized

What does that mean? How does the position data look like?

sorry for disturbing your mind，This refers to any position data that is not normalized，like:
this triangle position const array= new Float32Array([100 ,100 ,100 ,100, 200,100 ,100, 100 ,200])；
if code like this :
geometry.attribute.set("position",new BufferAttribute(array ,3 ,true));
then ：
If we obtain the mesh with this geometry through the ray, we will find that the obtained position is wrong

Your setup is actually not valid. The normalized attribute only applies to integer data, not float.

valid
I'm sorry, this was originally a problem in the gltf model. I used the wrong code for you to simulate. The InterleavedBufferAttribute is used in that gltf.

And thank you for letting me learn something new

I think this is related to #22874. It's not valid for float buffers but right now if a position or uv attribute are normalized with integer data then raycasting will not return a correct result. cc @donmccurdy.

Even if it's a PR, it's better to follow the discussion at #22874. Marking this as a duplicate.
