Mousepad (and others?) lose recent file list on reboot

I recently upgraded to XUbuntu 24.04 (Noble Numbat) from 22.04 LTS. Now my recent file list in Mousepad is lost on reboot. It is retained over stop/start of Mousepad.

I believe it is also the general XFCE recent file list that is lost. I cannot see any other report about this, though I would expect it to affect many people.

I am happy to provide further information if you let me know what is needed.
