Is there a way to execute InnerModuleEvaluation 12.d.iv.3? #156

Hi, I have been trying to write a test that checks #152

However, I can never get this line to execute. EvaluationError is always undefined at this point, and is set later. I believe this is because the child modules must resolve before the async root resolves, but that is also true for module, the sub-parent.

The closest I got was with two children, both throwing errors after a promise execution. Does this line ever get executed or can it be deleted?
