OSX: QSystemTrayIcon menu doesn't appear

Any use of context menu on a QSystemTrayIcon with Qt 5.8 beta or newer (old git clone of 5.8 doesn't have this issue) doesn't display any menu when clicking on the system tray icon on OS X 10.12.1 Sierra.

The system tray icon appears, but clicking it with left or right mouse button doesn't display the menu or the menu actions.

I tested with both Qt 5.8 branch from git and 5.8 beta. I didn't have this issue/bug with an earlier git clone of 5.8 branch (from a few months or so ago).

Since the systemtray demo/example doesn't put a context menu on the systemtray icon I've attached a small sample project that shows a QSystemTrayIcon with a menu. This works fine with Qt 5.7 (with patched qmake so it can build) and doesn't show the menu with Qt 5.8 bulit from git or 5.8.0 beta.
