title: Visual Studio Code does not render ipywidgets correctly
body: <p>I am having issue using Visual Studio Code.  the code seem to have issue with ipywidgets.
  the code is below (very simple interactive chart)</p>
  <pre><code>from ipywidgets import interact
  import ipywidgets as widgets
  import numpy as np
  import plotly.graph_objects as go
  @interact
  def foo(beta=(-10,10,1)):
      myx = np.arange(0,100,1)
      myy = myx *beta 
      print ('debug:',myy)
      fig = go.FigureWidget()
      fig.add_scatter(x= myx, y=myy)
      fig.show()
  </code></pre>
  <hr />
  <p>the same code works just as expected in Jupyter Notebook.
  I dig further and it seems:</p>
  <p>&quot;widgets require us to download supporting files from a 3rd party website. Error loading plotlywidget: ^4.14.3</p>

  <p>This is where I got stuck.. What's the next then to fix this issue?</p>
  <p>any guidance much appreciated</p>
  <p>thanks</p>
