Persp-mode automatically save buffer w/o physical file

[sfavazza]

I am not sure whether it is intended, but why persp-mode save buffers not baked by a physical file?

In some layout files I see lines containing the following: (def-buffer "<buffer-name>" nil <mode-they-where-active-at-saving-time>)

This causes an annoying hanging issue when trying to open a shell from the list of docker containers (see this issue).

Should I create an ad-hoc filter to prevent this or is it an unintended behavior?
