Fixes #43530

Is there a test to ensure that this in a property declaration isn't the same as this in a method/accessor?

let x = {
  foo: this,
  bar() {
    this;
  }
};

Not yet, I will add that case in.

These types of tests are kind of hard to read (and they only test the count), but this seems reasonable
