Using FQN rule in reference rules does not work as expexcted. [message #1837082]

I have the following parts in my grammar:

DynamicText:
	name=ID ":=" feature=[ecore::EStructuralFeature|QN] ("with" function=ID)
;
	
terminal QN:
	ID ('.' ID)+
;

the generated editor depicts that "DynamicText" could not be resolved.

var xxx := DynamicText.feature

I exspected " DynamicText.feature" gets parsed together as QN and then be compared to the scope provided here.

What is wrong ?

afaik estructural features are not in the index so it wont work with default scoping.
maybe you can try an eclass with QN + a separate reference for the feature.
or you do a reference to an epackage and do scoping for the qualified features manually.

Sorry, I didn't mentioned I have a custom ScopeProvider for this feature and that delivers exactly what you see "DynamicText.feature"
That is why I am wondering about this behavior
