Describe the bug
I saw that you are still working on implementing some of the new data types for the display entities like the Quaternionf, however one that isn't mentioned in the comment and you might not be aware of is org.joml.Vector3f, as the display entities use it in favour of the EulerAngle (aka Rotations) used in other places.
I am currently not aware of a different Converter / Wrapper than the Vector3F, which fails in this case.
Observed behaviour
java.lang.IllegalStateException: Invalid entity data item type for field 11 on entity b['Block Display'/1073741823, l='ClientLevel', x=44.09, y=72.83, z=-62.68]: old=( 0.000E+0 0.000E+0 0.000E+0)(class org.joml.Vector3f), new=ke@a39e8ed(class ke)
=> Class mismatch
