Description

Describe your context
Running in Google Colab

Describe the bug

Ran yesterday with if name == 'main': app.run(debug=True, mode='inline', port=8051) and displayed inline. Today, does not accept mode and does not run directly in Google Colab. Currently running if name == 'main': app.run(debug=True) but still does not display inline.

Expected behavior

Display directly inline in Google Colab.
