[wix-users] Dialog before cost initialize

[Fyodor Koryazhkin]

Hi,
According to my understanding you cannot create Feature condition based on
other Feature state or component state. This is because all features and
components states are resolved during CostFinalize standard action and you
do not know for sure what component/feature is resolved first.
