Describe the bug

When emitting TypeScript declarations, JSDoc comments attached to object properties (in either interface or type declarations) are indented incorrectly.

Given the following source:

export interface Options {
  /**
   * interface member
   */
  foo: string
}

The generated output is:

interface Options {
  /**
       * interface member
       */
  foo: string;
}

export { type Opttions };

Notice that the leading * inside the JSDoc block is over-indented, which breaks formatting and readability.

Expected output

interface Options {
  /**
   * interface member
   */
  foo: string
}

export { type Opttions };

interface Options {
  /**
-       * interface member
-      */
+   * interface member
+   */
  foo: string;
}
