Problems tab is not cleared after error has been fixed

Environment data

• VS Code version: 1.53.0-inside
• Jupyter Extension version (available under the Extensions sidebar): v2020.12.414227025
• Python Extension version (available under the Extensions sidebar): v2020.12.424452561
• OS (Windows | Mac | Linux distro) and version: Win10.18363 x64
• Python and/or Anaconda version: 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 23:03:10) [MSC v.1916 64 bit (AMD64)] on win32
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): N/A
• Jupyter server running: Local

Expected behaviour

Problems tab should clear all error messages after errors have been fixed in a jupyter notebook

Actual behaviour

Error messages remain in the problems tab until vscode is restarted (restart of jupyter kernel or re-opening the jupyter notebook file does not help)

Steps to reproduce:

1. create a new jupyter notebook
2. in the first cell add print "abc"
3. add a 2nd cell, add print("abc")
4. save
5. fix the error in the first cell

Logs

@DonJayamanne - not sure why you close this, this ticket was earlier an has clear repros…

@DonJayamanne this ticket was originally reported for 1.53.0-inside, I’m still on an insider build and although it feels like the problem might occur less frequently, I still observe it. So I still don’t understand why a ticket into which someone put some effort of providing repros gets closed as duplicate of a newer ticket.

But, whatever, then I’ll observe #5161 from now on.
