Sequencer- 'Dynamic Binding' SoftObjectPtr parameters fail to resolve after reloading editor

When reloading the editor and a level where a sequence has a dynamic binding with a soft object ptr parameter to an actor in the same level, the director blueprint will recompile on load of the level, but before the actors in the level are loaded, and the baked reference to the actor inside the director blueprint will be lost.
