WSL2 kali-win-kex always launches desktop in seamless mode

I've managed to successfully install Kali with WSL2 on a Windows 11 home machine. I've also managed to install (and reinstall) kali-win-kex. kex --win -s works as expected, but when I run

$ kex --sl -s

Two things happen: A Kali panel appears at the top of my Windows desktop as expected, but then a Kali (gnome) desktop immediately launches afterward and covers the Windows desktop.

The output (within Kali) from the command to run Kex in seamless is:

Starting Win-KeX server (SL)        Unable to find Win-KeX server (SL) running on host: 172.24.0.1  Win-KeX server (SL) stopped        Win-KeX server (SL) is stoppedStarting Win-KeX client (SL)        Unable to find Win-KeX server (SL) running on host: 172.24.0.1  Enabling Win-KeX client (SL)        xfDesktop started after 3 seconds        Enabling transparency now        Saving Win-KeX server (SL) session        Started Win-KeX server (SL)

How can I configure Kex or Kali to work correctly in seamless?
