🕗 Version & Regression Information

• This is a bug in 4.3.2-latest version
  When I use 'extract to method in class C' in following code， the selected region does not contain comment '/end/', but when I excecute 'extract to method in class C', the extractd method contains comment '/end/'. Is this a bug？I think it would better comment not selected appear in newMethod.

💻 Code

class C{
  a() {
    let z =1;
    /*start*/let a1= {x:1};
    let y =10;
    z=42
    return a1.x+ 10 /*end*/
  }
}

🙁 Actual behavior

class C{
  a() {
    let z = 1;
    /*start*/
    let __return;
    ({ __return, z } = this.newMethod(z));
    return __return; /*end*
  }
  private newMethod(z: number) {
    let a1 = { x: 1 };
    let y = 10;
    z = 42;
    return { __return: a1.x + 10 /*end*/
    , z };
  }
}

🙂 Expected behavior

class C{
  a() {
    let z = 1;
    /*start*/
    let __return;
    ({ __return, z } = this.newMethod(z));
    return __return; /*end*/
  }

  private newMethod(z: number) {
    let a1 = { x: 1 };
    let y = 10;
    z = 42;
    return { __return: a1.x + 10 , z };
  }
}

Reproduce the extract-to-method behavior from the linked TypeScript Playground using the supplied class C example, comparing the selected region with the generated method. Trace the extract-function refactoring entry point and add coverage for the trailing comment; done means the comment stays with the original return statement rather than appearing in the extracted method.
