Describe the bug
Komorebi panics and doesn't receive commands from komorebic if I maximize window and then try to move to another not maximized window using focus next.
Panic log message:

ERROR process_command{CycleFocusWindow(Next)}:focus_container_in_cycle_direction{direction=Next}:toggle_maximize:maximize_window: komorebi: panicked at 'removal index (is 1) should be < len (is 1)', komorebi\src\workspace.rs:859:42 panic.file="komorebi\\src\\workspac
e.rs" panic.line=859 panic.column=42

To Reproduce
Steps to reproduce the behavior:

Config to reproduce the issue:

#SingleInstance Force
#Include %A_ScriptDir%\komorebic.lib.ahk
#Include %A_ScriptDir%\komorebi.generated.ahk
WindowHidingBehaviour("minimize")
EnsureWorkspaces(0, 1)
EnsureWorkspaces(1, 1)
InvisibleBorders(0, 0, 0, 0)
FocusFollowsMouse("enable", "windows")
MouseFollowsFocus("enable")
ContainerPadding(0, 0, 0)
WorkspacePadding(0, 0, 0)
ContainerPadding(1, 0, 0)
WorkspacePadding(1, 0, 0)

FloatRule("exe", "Teams.exe")

CompleteConfiguration()

#j::
CycleFocus("previous")
return

#k::
CycleFocus("next")
return

#m::
ToggleMaximize()
return

Open 2 windows (I used alacritty).
Run komorebi.exe (v 0.1.14) with this config.
Wait until all setup commands from are executing.
Press Win+m to maximze one window.
Press Win+k to focus next.
Window will be changed but after that komorebi stops to receive any commands from komorebic.

Expected behavior
Komorebi continue to work fine
