This is also what happens if you choose to "decrypt" your
BitLocker
volume in Windows so if it is this case, cryptsetup doesn't support
it. We intentionally ignored this case mostly because it looked like a
small corner case (if you choose do decrypt the volume, Windows will
in the end fully decrypt the data and get rid of the BitLocker
volume/container), but if it's going to be a widespread use, we might
need to start looking into that. As Milan said, a reproducer and an
upstream issue for cryptsetup would be nice.
Unfortunately, I don't know a reproducer, other than "buy a Thinkpad".
I don't actually know much about Windows stuff.
