IStartable in a child lifetime scope causes recompilation of factory delegates

Describe the Bug

An IStartable that depends on a Func dynamic instantiation recreates and compiles the factory delegate anew for every lifetime scope. In the Gist, FactoryGenerator.CreateGenerator is called exactly once for LifetimeWithoutStartable and a total of four times—again once, but also once per lifetime scope—in LifetimeWithStartable.

Steps to Reproduce

Expected Behavior

I don't see a reason why the factory delegate cannot be reused for the startable and would prefer to not pay the expression creation, compilation and native code again and again for every child scope.
