SUMMARY

STEPS TO REPRODUCE
1. Use a Plasma X11 session.
2. In System Settings, configure Plasma session to automatically restore applications from previous session.
3. Start Kate.
4. Open a few text files in Kate.
5. Logout.
6. Start a new Plasma Wayland session. (Observation: Kate automatically starts and opens the same files from previous X11 session.)
7. Logout.
8. Start a new Plasma X11 session.

OBSERVED RESULT
Kate automatically starts, but looks like a fresh start: it doesn't open the files from previous session.

EXPECTED RESULT
Kate should automatically start and open the same files from previous Plasma Wayland session.
