tray icon don't close for ubuntu 18.04.3

[trae-op]

I used the code
app.on('before-quit', function (evt) { tray.destroy(); });
The app closes but icon stay tray.
Also when minimizing the app closes and I try open does not displayed.
For other OS like (mac-os, win-10), everything is OK.
electron: v6.0.1

I cloned electron-quick-start, added a tray, added the app.on('before-quit' code listed above, and pinned the Electron version in package.json to 6.0.1:

This gist works for me on Ubuntu 19.04 using the default gnome desktop -- the tray disappears when the application exits.

@trae-op, could you test this gist on your system?
