    Resolution Note:

    We need to consider a lot of changes in order to support this. Pausing playmode suspends a lot of the core Editor update, and the team in charge of that are not sure if it is a workflow they want to enable.

    I appreciate this is probably frustrating, as the situation you have hit is definitely a valid workflow with how Edit mode/Play mode works in the current version of Unity.
    While we are not fixing this issue right now, we are considering how this use-case fits into our larger vision for how the Edit mode/Playmode will evolve, in relation to prefab editing.
