Error on trying to inject an entry point script to another script

[shaked-okami]

I have the following scenario:
Script A is a mono behaviour, script A is dependent on script B.
Script B implements IStartable, and is registered before script A.
When the container tries to resolve script A, it crashes since it cannot resolve Script B.
this is very weird since i can enter the constructor of script B before crashing.
Is this suppose to behave like that??
