Labwc crashes on panel destruction with maximized & unmapped windows

[tokyo4j]

Problem description

Same root cause as #2937.

When a panel is destroyed immediately (<100ms) after a maximized window is unmapped, labwc crashes at assertion: labwc: types/xdg_shell/wlr_xdg_surface.c:168: wlr_xdg_surface_schedule_configure: Assertion 'surface->initialized' failed.

Stacktrace:

labwc: types/xdg_shell/wlr_xdg_surface.c:168: wlr_xdg_surface_schedule_configure: Assertion `surface->initialized' failed.

Steps to reproduce

1. Launch waybar
2. Run following commands:

git clone https://github.com/tokyo4j/wayland-demo.git -b remap
cd wayland-demo
make
./client & sleep 1; pkill waybar

3. Maximize the window before it's unmapped
4. When the window is unmapped and waybar is killed, labwc crashes
