Question WebGPU

### Description Sometimes we inherit from Three.js's light classes to create a …subclass with additional custom functions. This works fine in WebGL, but causes issues in the WebGPU renderer. WebGPU relies on the class's constructor to locate the lightNode, and when we create a new subclass via inheritance, this process breaks. Is this considered a bug? ### Reproduction steps empty ### Code empty ### Live example empty ### Screenshots _No response_ ### Version 175 ### Device _No response_ ### Browser _No response_ ### OS _No response_
