Mantaflow openvdb cache has wrong transforms when using adaptive domain

Mantaflow OpenVDB Caches produce problems when using the adaptive domain option. When importing the cached VDB into Blender u can see it "moving" and "scaling" as soon as the original adaptive domain gets bigger and transforms. It appears that the origin of the openvdb is the first vertex of the domain or the small indicator box for domain subdivision resolution.

The VDB should stay at the same place and don't scale or do other weird stuff. At the moment adaptive domain is not usable at all. Maybe it's a feature but it seems like a bug to me.

I'm not sure I understand the problem correctly.
Could you provide a simple .blend file demonstrating the issue?

I’ve seen, that the exact issue was already posted a few weeks ago. It is reported as a bug -> https://developer.blender.org/T79711

Sorry to have made a double post but the issue remains and is really annoying. We started to test blender for professional use and I came across that bug while working on a client project that needs a lot of smoke sims.
