I tested this again and it definitely is not happening, see below.
Reading the code, it seems the issue is that the save() function is
only ever called by the view() function when the answer is y/n but
never when the answer is p which is set by --force-pin.

I think that is correct given the output below.

Provided some debugging at the end of this mail.

Correct.

I hadn't read the FAQ, thanks for the pointer. In this case the pinning
issue would prevent it from working anyway.

I can only configure unattended-upgrades to run more often, there is no
option to ignore failure of a particular upgrade and retry it.

I see, that makes sense.
Here is the debugging for the pinning issue.
$ apt list --upgradable

NOTE: This is only a simulation!
apt needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
