The bug
In the overworld I bonemealed a warped fungus and when it grew it created floating warped wart blocks. This definitely appeared when the fungus grew.

Further and more thorough investigating concludes that this issue can be seen with both warped and crimson trees regardless of whether they're naturally generated or bone mealed. This affects 1.19 Release Candidate 2.

this is almost always because the fringe type has a 1/9 chance of being radius = 1 then radius = 2 so if that happens the vines layers (bottom 3 layers of the hat) are only diagonally connected to the main wart block structure of the tree and hence if any of the wart blocks fail to generate then you will result in a floating viens region.
this is especially prominent in trunk height 4 nether trees that feature the [1,2] fringe type as the top most layer of the vines region itself can be included in the fringe and hence have layer 1 which creates discontinuities in the bottom 2 vines layers as vines check for warts below them b4 generating and if there alr is a wart below the current selected block will have a 100% chance of generating so it going from 2 to 1 essentially resets the chain
Confirmed in 1.16 Pre-release 5.
