Prevent navigation to links in PDF file

[SimoneTosato]

I'm currently working with your PDFWindow and it's great except I can't prevent the navigation to an external link when it's clicked. My code to prevent the navigation is

app.on('web-contents-created',function(ev,wc){
  wc.on('will-navigate',ev=>{
    ev.preventDefault();
    wc.stop();
  })
})

and it's working on every window except yours. Am i doing something wrong or this is actually a bug?
