[Feature]: I want to know how to click the cors iframe in close shadow root

🚀 Feature Request

I see playwright can click the element in iframe with different domain. But now the iframe is inside the close shadow root. I can not use playwright to click the iframe. I have to write an chrome extension content script to access the close shadow root like:

(async () =>
{
    await new globalThis.Promise(_ => globalThis.setTimeout(_, 1000 * 60))
    const shadowRoot = chrome.dom.openOrClosedShadowRoot(document.querySelector('div[style*="display: grid;"] > div > div'))
    const iframe = chrome.dom.openOrClosedShadowRoot(shadowRoot.querySelector('iframe').contentDocument.body)
    iframe.querySelector('input').click()
})()

But querySelector('iframe').contentDocument will return null due to different domain. I want to know how playwright access the dom of iframe with different domain. So I can use it in my case.

Use javascript? Use chrome extension? or any devtools?

@fancy45daddy See #23047 for a workaround that turns all closed shadow roots into open shadow roots. Let me know whether this helps.
