Why is the menu in the title bar crazy?

Why is the menubar overwriting the name of my Electron app in the window in the Ubuntu desktop? It works fine for Atom, so it must be possible to get it right.

Next question --

Why is the menubar for my app so crazy?

Thanks in advance for any ideas...

Update #1

I tried the same experiment with the Quick Start app for Electron, with the same results.
