[🐛 Bug]: StackOverflowError when switching to Firefox window with opened print preview

[HSerg]

What happened?

Stack overflow error when switching to Firefox window with opened print preview. Most likely, the root cause is on the Firefox/GeckoDriver side, but the current selenium implementation endlessly tries to switch to the same problematic window causing stack overflow.

How can we reproduce the issue?

import org.openqa.selenium.WindowType;
import org.openqa.selenium.firefox.FirefoxDriver;

public class FirefoxStackOverflowError {

	public static void main(String[] args) {
		FirefoxDriver driver = new FirefoxDriver();
		try {
			String firstWindow = driver.getWindowHandle();
			driver.executeScript("setTimeout(function () { window.print(); }, 300);");
			Thread.sleep(2000);
			driver.switchTo().newWindow(WindowType.WINDOW);
			driver.switchTo().window(firstWindow);
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			driver.quit();
		}
	}

}

I have fixed the StackOverflowError, i would expect a NoSuchWindowException now.
The root cause is tracked in the mozilla issue above, so i will close this.
