DMN Decision Table - wrong evaluation of parameter named "product"

We have an input named "product" that is used in a decision table.
We upgraded to Drools 7.7.0.Final and noticed that now, what was evaluated was not the object passed as parameter, but an object of type ProductFunction.
The same issue is present in version 7.5.0.Final and 7.6.0.Final. It was working fine previously.

I think the issue is coming from the method getAllValues() of EvaluationContextImpl. Maybe the stack should be reversed before iterating over it and putting the values in the map.
