The working draft says in the prose:

A 3D rendering context is established by a a transformable element whose
computed value for transform-style is preserve-3d, and which itself is not part
of a 3D rendering context. Note that such an element is always a containing
block.

but we don't explicitly call this out under the transform-style property.

WebKit/Blink have this behavior because of a bug. Firefox seems to have copied
them or gone by the spec prose. Not sure what IE does.

The new spec text doesn't require that preserve-3d create containing block. I
don't think it should.
