System Tray does NOT disappear on console exit

[eugenesvk]

Running cargo run --example system_tray --features "tray-notification message-window menu cursor" and closing the console window via the X window button (or Alt+F4) doesn't remove the tray icon.

When you hover over it, it disappears

so it's a bit of an opposite to #261

Maybe it's a Windows bug but maybe your framework has found a way since that old answer
