[BUG] (Action) Selectors do not Work after Manual Content Setting

[Vinyzu]

Source code

• I provided exact source code that allows reproducing the issue locally.

Test file (self-contained)

import asyncio

# undetected-playwright here!
from playwright.async_api import async_playwright, Playwright

async def run(playwright: Playwright):
    args = []

    # disable navigator.webdriver:true flag
    args.append("--disable-blink-features=AutomationControlled")
    browser = await playwright.chromium.launch(headless=False,
                                               args=args)

    context = await browser.new_context()
    page = await context.new_page()
    await page.goto("https://raw.githack.com/microsoft/playwright-python/main/tests/assets/empty.html")
    await page.set_content('<a href="https://raw.githack.com/microsoft/playwright-python/main/tests/assets/one-style.html">yo</a>')
    await page.click("a")
    await page.wait_for_timeout(10000)

async def main():
    async with async_playwright() as playwright:
        await run(playwright)


if __name__ == "__main__":
    loop = asyncio.ProactorEventLoop()
    loop.run_until_complete(main())

Expected

The Selector should be able to pick up the new inserted content, like it is the case with "normal" playwright.

Actual

The Selector doesnt pick up the new content.
Note: Could be explained by a missing isolatedContext consideration.

Note:

await page.locator("a").click()

Works as expected.

[Vinyzu]

Note no.1:

await page.set_content('<iframe src="demo_iframe.htm" height="200" width="300" title="Iframe Example"></iframe> ')
print(page.frame_locator('[title="Iframe Example"]'))

Also doesnt work. Other Functions including Selectors maight also not be expected to work
