Error: Navigating frame was detached

Steps to reproduce

Environment:

Puppeteer 2.0.0; OS Windows 10; Node.js 12.0.0;

`const puppeteer = require(‘puppeteer’);

(async () => { const browser = await puppeteer.launch({ headless: false });

const page = await browser.newPage();
page.on('framenavigated', (frame) => {
    console.log('Frame navigated: ' + frame.name());
});

page.on('framedetached', (frame) => {
    console.log('Frame detached: ' + frame.name());
});

await page.goto('http://example.com');
await page.evaluate(() => {
    let iframe;
    iframe = document.createElement('iframe');
    iframe.name = 'my_frame';
    document.body.appendChild(iframe);
});

let frames = await page.frames();
let my_frame = frames[1];

try {
    await my_frame.goto('http://example.org');
} catch (error) {
    console.log(error);
}

try {
    await my_frame.goto('http://example.net');
} catch (error) {
    console.log(error);
}

await browser.close();

})();`

What is the expected result? Navigation should be completed without errors.

What happens instead? Error: Navigating frame was detached

@cssberries @dmnrmr could you try disabling the site-per-process flag?

const browser = await puppeteer.launch({headless: false, args: ['--disable-features=site-per-process']})

I was struggling with similar problem (frame detaching) on version 2.0.0. For whatever reason iframe I was interested for was detaching, and page.frames() returned an empty array and at the same time iframe was still there in the dom. So downgrading to 1.19.0 fixed the problem.
