Wouldn't the value of GetWidget()->delegate()->IsHidden() always be correct?

[lfg, 2017/05/05 18:53:02]

It's not correct for interstitials. It's also not correct for BrowserPlugin
based guests.

Acknowledged.

   params->never_visible = delegate_->IsNeverVisible();
   params->window_was_created_with_opener = window_was_created_with_opener;
   params->enable_auto_resize = GetWidget()->auto_resize_enabled();
