Here is a simple example.

Core code are shown below.

// src/index.ts
class Test {
  a: number
  b: number
  constructor() {
    this.a = 1
    this.b = 2
  }
  /**
   * C function
   * @param d Some d
   * @param e Some e
   */
  c(d, e) {
    this.a = d + e
  }
}

export default Test

// rollup.config.js
import path from 'path'
import pkg from './package.json'

import clear from 'rollup-plugin-clear'
import resolve from 'rollup-plugin-node-resolve'
import commonjs from 'rollup-plugin-commonjs'
import ts from 'rollup-plugin-ts'

/** @type import('rollup').RollupOptions */
const config = {
  input: path.join(__dirname, 'src/index.ts'),
  output: [
    {
      file: pkg.module,
      format: 'esm',
      exports: 'auto',
    },
  ],
  plugins: [
    clear({
      targets: ['dist'],
    }),
    resolve(),
    commonjs(),
    ts(),
  ],

  external: 'cesium',
}

export default config

// tsconfig.json
{
  "include": ["src/*"],
  "compilerOptions": {
    "outDir": "dist",
    "target": "ES5",
    "lib": ["ESNext", "DOM"],
    "declaration": true,
    "removeComments": false
  }
}

// dist/index.d.ts
declare class Test {
    a: number;
    b: number;
    constructor();
    /**
     * C function
     * @param d Some d
     * @param e Some e
     */
    /**
     * C function
     * @param d Some d
     * @param e Some e
     */
    c(d: any, e: any): void;
}
export { Test as default };

Expected Behavior

No needless comment.

Actual Behavior

Same two comments for one function.
