Unable to rearrange work features and component patterns in assembly browser in Inventor

Solution:

Starting from Inventor 2023.2 Update the work features can be moved. 

Alternatively, the following can be used to re-structure such components:

1. Add at least one dummy component right below the element you want to move in Inventor browser temporarily to have one movable component :

2. Do the reverse order: Move all the "normal" elements to the desired position.

3. Remove or delete the dummy component.
