System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.89

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2021-01-08 23:19, hash: 9c07454816
Worked: (newest version of Blender that worked as expected)

Short description of error
Smoke Domain is updated incorrectly or doesn't update at all) after transformations

Exact steps for others to reproduce the error
1 - create a sphere
2 - create Smoke Domain via Object>Quick Effects>Quick smoke
3 - move Smoke domain down
4 - click Play to start the simulation
In the place where the emitter was there was a density zone

If the Adaptive Domain option is enabled, the most unpredictable behavior is possible.

However, if you change any parameter on the Physics Properties tab, the Domain will update and the simulation will run as expected

As far as I can tell, this is not a bug. When I change the cache type to All, it works as expected. The cache type is set to Replay by default which will bake the simulation while the animation is played in the viewport. My guess is that it will bake for the first frame when the Quick smoke operator is used. More on the different cache types: https://docs.blender.org/manual/en/dev/physics/fluid/type/domain/cache.html#bpy-types-fluiddomainsettings-cache-type
