Bug [REGRESION] prefab unpacking during play doesn't work properly when a script with RequireComponent

is deleted in the scene.
error in console:

Error removing component when merging Prefab changes: Can't remove CharacterController because ThirdPersonControllerStrafe (Script) depends on it

major regression, in 2020.1.7 prefab works

This script was deleted, in fact all the components were but in 2020.2 character controller resurects by magic on play so then the prefab system tries to get rid of it again but that doesn't work because somehow the prefab system runs part of strafe.cs as it's unpacking this prefab
probably caused by

[RequireComponent(typeof(CharacterController))]

charactercontroller shouldn't be there but it reappears
