Starting with commit 2db94e2e we try to focus a fallback default focus window if no take-focus window candidate gets the input focus when we request it and we limit the focus candidates to the current window's workspace. However, if the window is unmanaging, the workspace might be unset, and we could end up in deferencing a NULL pointer causing a crash. So, in case the window's workspace is unset, just use the currently active workspace for the display.

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by GNOME Shell, the GNOME core user interface. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
