[Feature] `screenshot` methods can have a long delay

So basically I have noticed that screenshot functions can have a rather long delay before actually taking the screenshot.

try:
    if not page.locator("#foo").is_visible():
        raise Exception("failed to find element")
except Exception:
    page.screenshot()  # the element appears before it takes the screenshot because 'screenshot' is doing something that takes a long time
    raise

Wow, this is blazingly fast🔥! That’s amazing 🚀.

here’s a workaround to take a screenshot with no delay:

const base64 = (await (await page.context().newCDPSession(page)).send('Page.captureScreenshot')).data

it would be nice if playwright’s screenshot method had an option to behave like this
