* Output of `node_modules/.bin/electron --version`: 3.0.0
* Operating System (Platform and Version): macOS High Sierra 10.13.6
* Output of `node_modules/.bin/electron --version` on last known working Electron version (if applicable): 2.0.0

**Expected Behavior**
Hitting `Cmd+V` should paste the contents of the clipboard in the DevTools Console tab. 

**Actual behavior**
Nothing happens as if I haven't pressed anything.

**To Reproduce**
You can run any Electron app running 3.0.0 and the issue will be reproduced. I tried it with our own project and also a boilerplate project that contained nothing but the setup code to run the app.
atom/browser/common_web_contents_delegate_views.cc
if (autofill_popup_)
    autofill_popup_->Hide();
}
gfx::ImageSkia CommonWebContentsDelegate::GetDevToolsWindowIcon() {
  if (!owner_window())
    return gfx::ImageSkia();
  return static_cast<views::WidgetDelegate*>(
             static_cast<NativeWindowViews*>(owner_window()))
      ->GetWindowAppIcon();
}
#if defined(USE_X11)
void CommonWebContentsDelegate::GetDevToolsWindowWMClass(
    std::string* name,
    std::string* class_name) {
  *class_name = Browser::Get()->GetName();
  *name = base::ToLowerASCII(*class_name);
}
#endif
