method .is("*") returns different results for visual objects an concept

### Version of jArchi, Operating System
* Archi: 5.0.2.202304051112
* Platform: windows 10
* Javascript engine: GraalVM
* jArchi plugin: 1.4.0.202303211027

### Expected Behaviour
A test with .is("*") should return the same result for both visual objects as for concepts.

So far, I've seen this behavior only with the selector "*".
This didn't happen in a previous release. Don't know the jArchi version that introduced this error

### Actual Behaviour
The test with a visual object returns false.
The test with the same object selected in the model tree returns true

### Steps to Reproduce the Behaviour (with attached test files/script)
```
/**
* test .is()
*
* select an application-component on a view and run the script
* next select the application-component in the model tree and run the script
*
*/
console.log(`Result from .is("*") = ${$(selection).is("*")}`)
console.log(`Result from .is("application-component") = ${$(selection).is("application-component")}`)
```

Start with the provided script and the implementation of the .is() selector used by jArchi on visual objects and model-tree concepts. Reproduce the two selection cases in Archi 5.0.2 with the '*' and 'application-component' selectors, then verify that matching results are consistent for both object types.
