vscode: Debug console scrolls near top after each evaluated line after exception raised in debug console

Issue Type: Bug

See also https://github.com/Microsoft/vscode-python/issues/4725 - but note that vscode-python people say they

do not control the scrolling behavior of the debug console in VS Code

Expected behaviour

Debug console behaves normally

Actual behaviour

Debug console scrolls to top after each evaluated line

Steps to reproduce:

1. Save this code as Bug.py:

import sys
sys.exit()

1. Enable breakpoints at “Uncaught exceptions”
2. Debug Bug.py in VS Code
3. When hitting SystemExit exception, run print(1) in Debug console.
4. Run sys.exit() a bunch of times (1-5 times) in the Debug console.
5. Notice that at one point, Debug console scrolls to top
6. Scroll to bottom of Debug console output
7. Run print(2) in Debug console.
8. Notice that you don’t see 2 due to Debug console scrolling near top again.
