### 🐞 Description of the bug

I'm working in an ipynb file within VS-Code. Usually when creating a command I can tab through a popup menu of suggestions to complete the command. The menu appears but it only contains a few options.

### 📝 Steps to reproduce

```py
import ansys.fluent.core as pyfluent
meshing = pyfluent.launch_fluent(mode="meshing",ui_mode="gui")
watertight = meshing.watertight()
watertight.[I press tab here and see the following]
```
Menu options:
.children
.deletetasks
.first_child
.last_child
.load_state
.save_workflow
.task_names
.tasks

Start with the provided ipynb reproduction in VS Code, using the `watertight.[Tab]` completion point after launching Fluent in meshing mode. Compare the available suggestions with the expected command members and trace the completion behavior from that entry point. Done means the popup includes the appropriate command suggestions rather than only the listed subset.
