That looks reasonable. I don't know what it's *for*, but at least it's
not in a system-wide location that doesn't exist on a regular Debian
system.
In the OP it is not system-wide, but still unusual (overriden XDG_*
environment?): /home/mike/.cache/doc
Sanboxed applications running in mount namespaces may have no direct
access to your or system files. desktop-portal allows to selectively
expose some files on demand. An application sends a D-Bus request and
host opens file chooser.
