New decorators + Symbol.metadata issue

I was using bun-26436 but now upgraded to 1.3.10.

New decorators work, but not Symbol.metadata.

import type { Constructor } from "type-fest"

interface ControlOptions {
  path?: string
}

export function Control(path?: string): (value: Constructor<any>, context: ClassDecoratorContext) => void
export function Control(options?: ControlOptions): (value: Constructor<any>, context: ClassDecoratorContext) => void
export function Control(pathOrOptions?: string | ControlOptions) {
  return (target: Constructor<any>, ctx: ClassDecoratorContext) => {
    const path = typeof pathOrOptions === 'string' 
      ? pathOrOptions 
      : pathOrOptions?.path ?? '/'

    // Metadata logic here
    // In the new API, you might use ctx.metadata or a side-effect registry
    console.log(`Registering controller: ${target.name} at path: ${path}`)
    
    // Optional: Add metadata to the class context
    ctx.metadata.path = path
  }
}

@Control('auth')
class AuthController {
 
}

console.log(AuthController[Symbol.metadata])

Registering controller: AuthController at path: auth
undefined

Am I doing something wrong? Thanks.

Update

Apparently Bun still not provide the symbol metadata polyfill, or is not complete... I had to add this to the top of main.ts:

(Symbol as any).metadata ??= Symbol.for('Symbol.metadata');.
