WebVOWL currently treats domain classes in a different way than range classes. For the following example: ```ttl prefix : <https://example.com/> :simple rdfs:domain :From; rdfs:range :To. ``` WebVOWL will display the `:To` class but not the `:From` class. Expected: classes specified in domain and range to be treated/visualized in a similar way. Workaround: add at least one statement about the `:From` class (e.g., `:From a owl:Class`).
