Bug description

Hey.

Just a minor issue.

Sometimes (see #12509) I do have to SIGHUP Cinnamon (from the kernel console) after which a popup window asks me whether I want to restart Cinnamon (where I click yes).

After that, most windows are shifted to the top (some, e.g. maxmised ones, partially outside of the screen).

Steps to reproduce

1. Switch to the kernel console & log in.

2. # pgrep -a cinnamon
   4726 /usr/lib/x86_64-linux-gnu/cinnamon-session/cinnamon-session-binary --session cinnamon
   4907 cinnamon-launcher
   4953 cinnamon --replace
   5025 cinnamon-killer-daemon
   

3. Here I SIGHUP the one with --replace, i.e. kill -HUP 4953
4. Switch back to X.
5. Click Yes when Cinnamon asks whether it shall restart.

Expected behavior

Windows should ideally stay in the same position/state as they had when Cinnamon "crashed".

Additional information

No response

Start with the Cinnamon process launched with --replace and reproduce the SIGHUP restart sequence from the listed steps. Trace the restart path and window placement behavior, then verify that windows retain their previous positions and states, including maximized windows.
