Preview missing in Google Colab

[au5tr1ng3r]

Additional code snippet pop-up that didn't used to occur:

from google.colab import output output.enable_custom_widget_manager()

Despite passing this, preview still missing.

I didn't pass this code an the preview is working normally.

It wasn't working for me either but now it is with 0.12 - not sure if I was using an older version before.
