Azure ML Portal Notebook does not show widgets from ipywidgets

Using ipywidgets in an Azure ML Portal Notebook as shown in the following example does not show an interactive widget.

```
from ipywidgets import interact

def f(x):
return x

interact(f, x=10)
```
Switching inside the Azure ML Portal to the JupyterLab Notebook editor and pasting the same code an interactive widget does appear.

Note: This simplest form of slider does work on Azure ML Portal Notebooks:
```
from ipywidgets import widgets

widgets.IntSlider()
```

ipywidgets version:
7.6.3

未識別出 repository 檔案或測試。首先在 Azure ML Portal Notebook 中重現 interact 範例，並將其與 JupyterLab 中的相同程式碼進行比較；當互動式 widget 在 Azure ML Portal 編輯器中呈現，同時保留正常運作的 IntSlider 行為時，即視為完成。
