Actual Behavior -

hang up when getting cookies on newly opened window.

Steps to reproduce -

1. Create WebDriver instance.
2. open first window by e.g. driver.get()
3. open another window by e.g. executing JavaScript “window.open()”.
4. switch to newly opened windw.
5. try to get cookies.

following Java and python code my reproduce this issue. (python version needs remote IE webdriver stup)

Java:

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class GetCookiesOnAnotherWindow {
    public static void main (String[] args) {
        WebDriver driver = new InternetExplorerDriver();
        try {
            driver.get("about:blank");
            ((JavascriptExecutor) driver).executeScript("window.open('about:blank', 'another_window')");
            driver.switchTo().window("another_window");
            driver.manage().getCookies(); // <- IE Driver hangs here
        } finally {
            driver.quit();
        }
    }
}

Python:

# coding=utf-8
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

try:
    caps = DesiredCapabilities.INTERNETEXPLORER.copy()
    driver = webdriver.Remote(desired_capabilities=caps)
    driver.get("about:blank")
    driver.execute_script("window.open('about:blank','another_window')")
    driver.switch_to.window('another_window')
    cookies = driver.get_cookies() # Hang up HERE.
except Exception:
    pass
finally:
    driver.quit()
