Why can't I see some puppeteer calls in the protocol monitor?

[vsemozhetbyt]

Steps to reproduce

Tell us about your environment:

• Puppeteer version:3.3.0 (chromium_revision 756035)
• Platform / OS version: Windows 10 x64
• Node.js version: 15.0.0-v8-canary20200603908772e6f4

What steps will reproduce the problem?

'use strict';

const puppeteer = require('puppeteer');

(async function main() {
  try {
    const browser = await puppeteer.launch({
      headless: false,
      defaultViewport: null,
      args: ['--lang=en', '--start-maximized'],
      devtools: true,
    });
    const [page] = await browser.pages();

    await page.goto('https://example.org/');

    await page.waitForFunction(
      () => window.protocolMonitorEnabled === true,
      { timeout: 0 }
    );

    // Here I toggle the protocol monitor on, open it,
    // run 'window.protocolMonitorEnabled = true'
    // and click on the page to transfer the focus from the DevTools (just in case).

    await page.waitFor(10000);
    await page.mouse.click(100, 100);

    await page.evaluate(() => {
      document.title = 'New title';
    });
  } catch (err) {
    console.error(err);
  }
})();

What is the expected result?

A bunch of Input.dispatchMouseEvent method calls before the title change.

What happens instead?

No Input.dispatchMouseEvent method calls:

(Let me know if I should post this to devtools protocol issues or if I am completely wrong about a possibility to listen to the calls from the puppeteer in such way.)
