Steps to reproduce

I just use playwright's python bindings, and here's my test code.

from playwright.sync_api import sync_playwright
true = True
false = False
cookies = [
    {
        "domain": ".example.com",
        "hostOnly": false,
        "httpOnly": false,

def test_cookie():
    with sync_playwright() as p:
        browser = p.chromium.launch(headless=False)
        context = browser.new_context()
        print(f"===Cookies before adding: {context.cookies()}===")
        context.add_cookies(cookies)
        print(f"===Cookies after adding: {context.cookies()}===")
        assert context.cookies() == cookies
        context.close()
        browser.close()
if __name__ == "__main__":
    test_cookie()
    print("===Test completed successfully.===")

Expected behavior

Cookies after adding will be the same as cookies variable, and pass the assert.

Actual behavior

Cookies after adding is [{'name': 'g', 'value': 'filtered', 'domain': 'h5.xxx.example.com', 'path': '/', 'expires': -1, 'httpOnly': False, 'secure': True, 'sameSite': 'None'}] . So there's an AssertionError.

Additional context

~Maybe httpOnly field causes that bug? I found only "g" set that field to true.Is this expected behavior?~

Edit: set that field not work :(
