Parameter decorator applied on a symbol method cannot acquire the method instance

[CMCDragonkai]

Describe the bug

When using a parameter decorator such as:

function context(target: any, key: string | symbol, index: number) {
  const method = target[key];
  console.log('WHAT IS THIS?', method);
  // The `method` should not be undefined
}

const symbolFunction = Symbol('sym');

class X {
  regularFunc(@context ctx) { }

  async asyncFunct(@context ctx) { }

  [symbolFunction](@context ctx): Promise<void> {
    return new Promise((resolve) => void resolve());
  }
}

We get an output like:

WHAT IS THIS? [Function: regularFunc]
WHAT IS THIS? [AsyncFunction: asyncFunct]
WHAT IS THIS? undefined

This does not occur on tsc. With tsc (via ts-node), we get:

WHAT IS THIS? [Function: regularFunc]
WHAT IS THIS? [AsyncFunction: asyncFunct]
WHAT IS THIS? [Function: [sym]]

Input code

function context(target: any, key: string | symbol, index: number) {
  const method = target[key];
  console.log('WHAT IS THIS?', method);
  // The `method` should not be undefined
}

const symbolFunction = Symbol('sym');

class X {
  regularFunc(@context ctx) { }

  async asyncFunct(@context ctx) { }

  [symbolFunction](@context ctx): Promise<void> {
    return new Promise((resolve) => void resolve());
  }
}

Expected behavior

It should show:

WHAT IS THIS? [Function: regularFunc]
WHAT IS THIS? [AsyncFunction: asyncFunct]
WHAT IS THIS? [Function: [sym]]

Actual behavior

WHAT IS THIS? [Function: regularFunc]
WHAT IS THIS? [AsyncFunction: asyncFunct]
WHAT IS THIS? undefined
