Steps to Reproduce:

1. Add JSDocs to an interface, and implement that interface in a class

interface Sample {
  /** 
   * Does some important work
   * @param name Name of employee working
   * @param age Age of employee
   */
  doWork(name: string, age: number): void;
}

let s: Sample;


class Concrete implements Sample {
  doWork(name: string, age: number) {
    // Nothing to do
  }
}

let c: Concrete;

2. Attempt to access intellisense for the class, and notice the @param information has not been picked up from the interface.

Does this issue occur when all extensions are disabled?: Yes

Reproduce the interface and implementing class example, then inspect the completionEntryDetails path used by IntelliSense for the class method. Compare the parameter documentation shown for the interface with that shown for the implementation. Done means the implementation's completions include the interface's @param descriptions, with coverage for the reported example.
