• Successfully reproduced against the latest version of NW.js?

Current/Missing Behavior

When running a nw.js application offering a tray icon directly on Wayland (--ozone-platform=wayland), the tray icon is its own separated window. On Gnome, it means we can switch on it with alt-tab and have a big icon as a window, on a tiling window manager/compositor it means we get a tile for the tray icon itself.

Expected/Proposed Behavior

The tray icon should be set in the tray icon place if one exist, but clearly not be a window on its own.
