Only one output rendered

[sglyon]

If I run a code cell that has multiple outputs, only the first one is rendered in the output area.

To reproduce go to the thebe demo, activate the kernel, and replace the contents of the code cell with something like

print("Hello")
print("world")
print(1234)

and click run

When I do this, I get the following:

NOTE

If I click run many times, occasionally I will see all 3 outputs, but often it is just one

Thanks for reporting this @sglyon
Looks like this might be specifically related to thebe-lite as that demo is using the juptyerlite/pyodide back end.

this binder example works as expected:
https://jupyter-book.github.io/thebe/binder.html

also I note that if I hit Run multiple times on the thebe-lite demo that you linked to originally, I intermittently get the wrong/right output, until the session dies.

Hey @stevejpurves the note about being specific to jupyter-lite sounds right to me

The trouble is that this is the backend I'm using in my project!

Do you have any suggestions for how we can track down this error. I'm happy to investigate more, but would be forced to inefficiently wander around the thebe/pyodide/jupyterlite/jupyterlab codebases to hunt it down

This is affecting me, too, and it is quite annoying. It occasionally helps to do a time.sleep(0.1) at the end of a cell, but not consistently. Would somebody have any pointers on where would be a good place to start looking?

Hi @stevejpurves sorry to ping this, but we are still seeing the issue.

Do you have any suggestions on where we might be able to dig/look to get it fixed?
