Error message not shown when using a callback!

See original GitHub issue

Using JupyterLab 1.1.4

When using a simple code snippet like this

from IPython.display import display
from ipywidgets import widgets
button = widgets.Button(description="Click Me!")
display(button)

def on_button_clicked(b):
    a=1/0
    # do something important

button.on_click(on_button_clicked)

and I run the code and click on the button, I do not get any error message! There is clearly an error, but I do not see it in any output!

Will this bug fixed in a future release?

And we are very grateful for @mbektasbbg for implementing the log console in JupyterLab 1.2 (and his employer Bloomberg for prioritizing him to work on it) so that we could move back to showing errors and output by default!
