Terminal Task Tab Status not working anymore

[JohnDoe2991]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.67.2
• OS Version: Windows 10 21H2

Tasks in the terminal tab don't show "running" or "error" indicator anymore, which got introduced here: #121659
It does not work within Windows/Powershell and WSL2/bash.

Steps to Reproduce:

1. Add simple tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "sleep 2 seconds",
            "type": "shell",
            "command": "sleep 2",
            "group": "none",
            "problemMatcher": []
        },
        {
            "label": "sleep 2 seconds and fail",
            "type": "shell",
            "command": "sleep 2; exit 1",
            "group": "none",
            "problemMatcher": []
        },
    ]
}

2. run "sleep 2 seconds", on first run there is the "running" indicator followed by the "check" indicator
3. run "sleep 2 seconds" again, no "running" indicator
4. run "sleep 2 seconds and fail", no "running" indicator, "check" indicator disapears, no "error" indicator

I've also tested older versions:

• 1.63.2
  • "running" indicator working correctly
  • "error" indicator not working
  • 
• 1.58.2
  • everything is working as expected
