progress bars not displaying in vscode Jupyter notepad

A few days ago fastprogress stopped working in Jupyter notepads in vscode.

It seems to run without error but does not display anything.
I have the same issue in existing environments (venv) and in newly created environments.
I have reverted to Jan 2023 version of vscode where I know it was working before, but that showed no change.

Running the following code works for console output, but in Jupyter notebook nothing.

Where should I look to try and resolve this issue? Any guidance will be valuable because I have pretty much exhausted my knowledge of fastprogress and what I can do.

```
from time import sleep
from fastprogress.fastprogress import master_bar, progress_bar

mb = master_bar(range(10))
progress_bar(range(100), parent=mb)

for i in mb:
for j in progress_bar(range(100), parent=mb):
sleep(0.01)
```
