Live share: Guest hang at "Executing Cell" and no output in "Python Interactive" window

[xiaofeng0123]

Environment data

• VS Code version: 1.39.0-insider
• Extension version (available under the Extensions sidebar): python 2019.10.38574-dev
• Live Share version: 1.0.869

Expected behaviour

Run cell successfully and the output of the cell shown on "Python Interactive" on Guest

Actual behaviour

Guest hang at "Executing Cell" and no output in "Python Interactive" window. Host works OK.

Steps to reproduce:

1. Open the file manualTestFile.py in VSCode(download manualTestFile.py from https://github.com/IanMatthewHuff/vscode-python/blob/99cc5641c9d58b4059f939d015ac21f3095276b6/src/test/datascience/manualTestFiles/manualTestFile.py )
2. On the first cell click "Run Cell"
3. Start live share
4. On Guest, click "Run Cell"

If you needed, please refer to below live env:

Yeah, the basic scenarios seem to work if you connect live share and then start up the interactive window. But I can repro this issue. Since the connection happens later it seems like the "catch up" code to sync up the guest with a host that has already executed might have an issue.
