Selenium with Chrome Headless fails to get URL

Question

In my test script I simulate the click on a button, which generates and opens a PDF in a new Chrome tab.

//Imprime consulta
IWebElement btnGeraPDF = driver.FindElement(By.Id("id"));
btnGeraPDF.Click();
Thread.Sleep(4000);

//Aguarda fechamento da página em branco da geração do PDF
driver.SwitchTo().Window(driver.WindowHandles.Last());

var urlAbaAtual = driver.Url;
var urlPaginaGeracaoPDF = ".../PDF.ashx?PdfId"; 

while (urlAbaAtual.Contains(urlPaginaGeracaoPDF))            
   Thread.Sleep(2000);

This excerpt works correctly when running the script, except for in headless mode.

Error occurs:

The HTTP request to the remote Webdriver server for URL http://..... timed out after 60 Seconds. -> The request was aborted: The Operation has timed out.

The Exception is displayed in the excerpt driver.Url.

It is the same problem portrayed at this link, except that I don’t use Specflow.

I’ve searched the List of Chromium commands but I haven’t found anything that can solve this problem.

Has anyone ever gone through the same? I currently use these headless commands:

ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-infobars");
options.AddArguments("--start-maximized");
options.AddArguments("--headless");
options.AddArguments("--log-level=2");
options.AddArguments("--lang=pt-br");
