#### ALL software version info

It seems that panel is not working correctly when it comes to updating based on a slide

#### Expected number of stars to change when slide number changes

#### 

```python
import panel as pn

pn.extension()

def model(n=5):
    return "⭐" * n

slider = pn.widgets.IntSlider(value=5, start=1, end=5)
interactive_model = pn.bind(model, n=slider)
layout = pn.Column(slider, interactive_model)
layout.servable()

```

Can you try trying it out with `layout.show()` and if that doesn’t work, do you have any browser console errors?

```auto
layout.show()

```

works since it shows things in a browser (when i execute with local kernel), however since I work in a remote kernel (without ssh), i can’t really see the localhost created
