Bug: [v8] When adding onRender to a class extension, it does not work as expected

[adam-savard]

Current Behavior

Currently, if you have a class that extends a Pixi object, say:

class SomeClass extends Container{}

And then you add a class definition for onRender like so:

class SomeClass extends Container{

onRender(){
    console.log('This will not work');
}

}

It won't work; this seems to be because of getters and setters being used for onRender under the hood.

What you have to do instead is:

class SomeClass extends Container{
constructor(){
    super();
    this.onRender = () => {
        console.log('This will work');
    }
  }
}

Expected Behavior

Overriding with class definitions should produce the same result, or at least this behavior should be documented

Steps to Reproduce

The steps are listed above!

Environment

• pixi.js version: 8.0.2
• Browser & Version: Chrome Version 122.0.6261.128 (Official Build) (64-bit)
