Unable to view image attachments in Markdown cells

[DonJayamanne]

In Classic Jupyter one can insert images into markdown cells. The images are stored as base64 encoded metadata in the corresponding notebook cell.

The value in the markdown is as follows:
![Screen%20Shot%202021-05-04%20at%2016.23.48.png](attachment:Screen%20Shot%202021-05-04%20at%2016.23.48.png)

Note the attachment:Screen% above

We don't display these images today.
The menu option is Edit->Insert Image (applies to markdown cells).

This way images are stored in the notebook (self contained, just like output).

Yes, unfortunately it is still a bug. I am unable to add embedded image to the markdown and also unable to see the existing ones.
It makes the notebook functionality totally unuseable for me.
