1.install latest VS code
2.open the any notebook(ipynb file),there will be no vertical scrollbar for long outputs
The below image is actual behavior means the vertical scrollbar not shown although the output is pretty long.

Please provide as much info as you readily know
The console output is in attached file.
temp.txt
We actually already have this option, but it doesn't seem to be working
python.dataScience.maxOutputSize
This is a regression.
So,are we getting the solution in next release?
Yes. It was merged into master yesterday so our next release will have the fix for this.
Validated. Tested on windows. Long output now trimmed at the maxOutputSize setting so you can actually see the next cells. Also checked that -1 allows for infinite output size.
yup now its working on VS code insider with python extension(insider),so when we got it in stable release?
The next official release will be in November. We're trying for a point release in the next week.
