Content assist with reference is broken when the same rule is possible in context twice

[cdietrich]

given the grammar

entry Model:
    'model' name=ID '{'
        enitities+=Entity*
        elements+=Element*
    '}';

Entity: "entity" name=ID "{"
    fields+=Field*
    '}';

Field:
    name=ID;

Element:
    name=ID ":" type=TypeWithEverythingAndSauce;

TypeWithEverythingAndSauce:
    InlineType | Type | FieldType;

InlineType:
    {infer InlineType} 'inline' '<' '{' '}' '>';

BuiltInType infers BuiltInType:
    TextType |
    NumberType;

TextType infers DataType:
    name='Text';
NumberType infers DataType:
    name='Number';

FieldType:
    'field''<' entity=[Entity:ID] '.' field=FieldRefOrBuiltInField'>';

Type:
    BuiltInType | FieldType;

FieldRef:
    field=[Field:ID];

BuiltInFieldId infers BuiltInField:
    name="id";

FieldRefOrBuiltInField:
    FieldRef | BuiltInFieldId;

and scope provider

export class HelloWorldScopeProvider extends DefaultScopeProvider {
    override getScope(context: ReferenceInfo): Scope {
        if (isFieldRef(context.container)) {
            if (context.property === "field") {
                return this.createScopeForNodes(context.container.$container.entity.ref?.fields || []);
            }
        }
        return super.getScope(context);
    }
}

content assist does not work here

model mymodel {
    entity MyEntitiy { yyyy}
    xxxx: field<MyEntitiy.|yyyy>
}

when removing the redunant FieldType from TypeWithEverythingAndSauce it works as expected
