the class EmbeddedDisplayRepresentation method dispose.

@Override

    // could dispose a representation that hasn't been represented, yet.
    // Fetching the embedded model from runtimePropEmbeddedModel

    // 
    // --> Very unlikely to happen because runtime has been stopped,
    // so nothing is changing the file name right now.
