Tray menu is not working on Linux

NWJS Version : v0.31.4 default/sdk and previous.

Operating System :

1. Linux 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux
2. Linux 4.14.44-1-MANJARO #1 SMP PREEMPT Fri May 25 18:35:59 UTC 2018 x86_64 GNU/Linux

Tray icon should be shown, but it is not.

var trayOptions = {
    icon: 'images/ic_launcher_20.png',
    click: function () {
        win.show();
    },
    title: __('about_plain_text')
};

converse.tray = new nw.Tray(trayOptions);
var submenuMainTray = new nw.Menu();

quitAll.click = function () {
   closeMe();
};

submenuMainTray.insert(quitAll);

Just found this old thread. Looks like we still have this problem.

Operating System: Manjaro Linux

Qt Version: 5.15.1
Kernel Version: 5.9.1-1-MANJARO

Tray icon is there, tooltip is there, popup messages are there, but the menu does not show up.

I have tested several NW versions and found that NW 0.40.2 was the latest version the menu is working for me. So:

NW 0.40.2: tray menu ok
NW 0.41.0 - 0.49.0: tray menu not ok

@rogerwang Any ideas how to fix this? It looks like NW 0.40.2 is the last version with a menu on Linux and 0.50 added support for wayland so having to choose one or the other right now.
