def iframe_test():
    with sync_playwright() as p:
        browser = p.chromium.launch(headless=False)
        page = browser.new_page()

        child_frame.locator("#u_5_6").click()

        browser.close()

Steps

• run the method - iframe_test using the undetected_playwright package
• then try to run the same method using the original playwright package

Expected

• After the website is loaded, it should be able to click the two buttons specified

Actual

• However, nothing happens if I'm using the undetected_playwright package, the code didn't even recognize the iframe; on the other hand, the method with original playwright runs with no problem

doubling up on this issue, looks like you can't do anything with the iframe, calling frame.content() get you an undetected_playwright._impl._errors.Error: Unable to retrieve content because the page is navigating and changing the content.

using undetected-playwright-patch==1.40.0.post1700587210000 vs latest playwright==1.44.0
