Wait Timeout Issue.

[jagxman]

Using this will cause timeout issues with headless set to true. Can be recreated with Multi-Threading and having the following code on a login page.

Ex Code:

try
{
await page.WaitForSelectorAsync("#loginUsername");
}

catch (WaitTaskTimeoutException)
{
Console.WriteLine("Timed out.");
    await browser.CloseAsync();
  
}

Using default Puppeteer does not have this issue.
