User prompt dialog events are emitted twice

[OrKoN]

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch({
  protocol: 'webDriverBiDi',
  headless: false,
});

const page = await browser.newPage();

page.on('dialog', async dialog => {
  console.log(dialog.type);
  await dialog.dismiss().catch((err) => console.error('dismiss failed', err))
});

await page.goto('https://htho.github.io/wdio-repro-collection/iframeNavigation.html');

await page.evaluate(() => {
  alert('test');
});

await browser.close();

Expected:

On dialog handler is invoked once.

Actual:

On dialog handler is invoked twice, the second dialog dismiss call fails since it was already handled.
