Ipywidgets: 'Style not applied because a parent view does not exist' on Chrome, Google Colab,

[safak17]

I am using Google Colab Jupyter Notebook on Chrome. The styles and layouts of the widgets are not updating. Nothing changes!

import ipywidgets as widgets
from ipywidgets import *
from IPython.display import display

b1 = widgets.Button()
b2 = widgets.Button()

AppLayout(left_sidebar = b1,
          right_sidebar = b2)

Here is what I get as the output on Google Colab Jupyter Notebook.

And this is the Chrome console output.

How can I solve this?

CC @blois, who works on colab.

(This issue is probably better filed on the google colab repo: https://github.com/googlecolab/colabtools)
