"Terminal: Clear" not working as desired

Steps to Reproduce:

1. Run a python file using command palette >Python: Run file in terminal window
2. Terminal shows the output. Now, clear the terminal using command palette >Terminal: Clear
3. Terminal gets clear now. Run the file again in the terminal >Python: Run file in terminal window
4. Here is where issue shows up - the terminal still shows all the previous outputs from before the last clear command. IMO, desired should be that terminal should not show any previously cleared outputs.
5. Attached below is a gif of the screen reproducing & visualizing this issue

Does this issue occur when all extensions are disabled?: Yes, the issue reoccurs. (Note: All except the “Python” extension were disabled. Python extension is needed to run the python file in terminal.

I had also posted in Super User forum thinking this was some issue with my system. And then I tried it on a clean build of VS code and it got repeated. Hence, I decided to post it as a bug.

It’ll be fixed by work on the ConPTY API that’ll be tracked by microsoft/terminal#1193.

@mrkarthi I suggest we don’t bump this issue anymore, because it’s already marked as an upstream problem.

But anyway, feel free to add your thumbs up to this and the upstream issue to add priority to them.
