App doesn't quit without active window

[oaleynik]

See the attached zip for example.
nw-app-quit-bug.zip

The app in the attached zip has javascript file as an entry point.
After 3 seconds there is an attempt to close application using nw.App.quit() - app doesn't quit.

If uncomment nw.Window.open('index.html', {show: false}, function () {}); app will quit successfully.

I can reproduce this issue on Linux/Mac with nwjs-sdk-v0.23.5.

I'm still experiencing this on macOS Sierra 10.12.6 with nwjs-v0.35.5.

I'm trying to build a windowless tray icon app. I stripped it down to minimal reproduction code, which doesn't even need a setTimeout:

// package.json
{
  "name": "tray-test",
  "main": "index.js"
}

// index.js
// Uncomment this line and the app quits as expected.
// nw.Window.open('', {show: false});
nw.App.quit();
