Shutdown dialog is not destroyed in Limbo x86 PC Emulator

Environment: Android 6.1 netbook with Limbo emulator 4.1.0 app installed

Setup is the same as you could see in any qemu vm:
-machine pc -cpu qemu32 -m 128 -vga std etc

ReactOS starts and runs a bit slower but still usable, the problem comes when you attempt to restart/shutdown the system. Does not matter the way you using (start menu, taskmgr, shutdown command) always ReactOS keeps waiting forever (the system don't hangs, because shutdown dialog animation keeps playing and mouse pointer can be moved around) even you can break into debugger and then type "cont" to get back to the system.

My regtest result is that since 20190224-0.4.12-dev-733-g8c90a67 the issue is present.

Seems that the dialog window sets a timer, but that timer cannot be killed and then keeps waiting forever.
