Unable to Test First Example on tsdoc.org Playground

Hi TSDoc Team!

I couldn't test the very first example on tsdoc.org's site. It generates an error because it starts with a class instead of a comment. Was this the expected behavior?

Thank you for your attention.

export class Statistics {
  /**
   * Returns the average of two numbers.
   *
   * @remarks
   * This method is part of the {@link core-library#Statistics | Statistics subsystem}.
   *
   * @param x - The first input number
   * @param y - The second input number
   * @returns The arithmetic mean of `x` and `y`
   *
   * @beta
   */
  public static getAverage(x: number, y: number): number {
    return (x + y) / 2.0;
  }
}

(1,1): Expecting a leading "/**"

Reproduce the first example in the tsdoc.org Playground and inspect the (1,1): Expecting a leading "/**" error. Determine whether the example or Playground behavior is wrong; done means the expected behavior is confirmed and the example can be tested or clearly explains the required input.
