🐛 Bug Report
This works in Puppeteer 20, but not 21. The error appears with toMatchElement and toMatchTextContent
● static: iframe › should load iframe page
[object Object] is not supported
59 | });
60 | it('should load iframe page', async () => {
> 61 | await expect(iframe).toMatchTextContent('Framed page');
| ^
62 | });

64 | it('should load the content script, once', async () => {

To Reproduce
I think:
await page.goto('https://static-ephiframe.vercel.app/Parent-page?iframe=./Framed-page');
const elementHandle = await page.waitForSelector('iframe');
const iframe = await elementHandle.contentFrame();
await expect(iframe).toMatchTextContent('Framed page');Expected behavior
The test should pass

Since v21 has been released after the last jest-puppeteer release, I assume this version hasn't been tested here.
This started happening again with puppeteer 21.2.1.
(It looks like 21.1.1 is OK, so should be easier to downgrade and bisect.)
Hi, if we can do something in this repository to fix it, feel free to submit a PR.
#566 should fix this
