chromedp – cannot get current window title

[Andreas]

Chromedp is used for browser automation. I try to get windows title on gmail inbox page after it was opened. 

For some reason the title is empty. What am I doing wrong?

```

...

var title string

err := chromedp.Run(taskCtx,

chromedp.Navigate(`https://mail.google.com/mail/u/0/h/`),

...

chromedp.WaitVisible(`body`), // gmail inbox page was opened in browser

chromedp.Title(&title),

)

if err != nil {

if err.Error() == "context deadline exceeded" {

log.Println(err) // this line executed

} else {

log.Fatal(err)

}

}

log.Printf("success.\ntitle: %s\n", title) // title is empty!

```

The output in console:

2019/10/22 08:01:49 context deadline exceeded 
2019/10/22 08:01:49 success.
title:

I run it in normal browser mode (no headless) so the page was opened. Even if I try to get some element text there is empty value too, for example selector like this one:

//div[@id="gbar"]/a[contains(@class, "gb1")]
