Trait properties and methods ignored

[injecteer]

Using
Eclipse Build id: 20230608-1333
Eclipse Groovy Development Tools 5.0.0.v202306301519-e2306

For a class:

import grails.gorm.annotation.Entity
import grails.mongodb.MongoEntity

@Entity
class Game implements MongoEntity<Game> {}

where the MongoEntity defines the methods like:

@CompileStatic
trait MongoEntity<D> implements GormEntity<D>, DynamicAttributes {
    static MongoCollection<Document> getCollection() {
        currentMongoStaticApi().getCollection()
    }
}

If I use the class in the code:

it compiles and runs just fine, but the trait methods are underlined as "unknown" and also not resolved in autocomplete.
