Steps Bug 1:

• clone https://github.com/hediet/vscode-debug-visualizer/
• Run Tasks: Run Task

Actual result:

Expected result:

• npm: dev - extension should not appear twice
• every entry should have details, not just npm: dev - webview

Steps Bug 2:

• Run both of the dev - extension tasks (kill the other before running each)
  • Notice that one of the tasks does not pick up the problemMatcher configured in tasks.json (VS Code shows the loading indicator forever in that case)

Steps Bug 3:

• Use extension API vscode.tasks.fetchTasks to query all tasks
  • Notice that the name of the first duplicate is npm: dev - extension (as configured in tasks.json) and the other is just dev - extension

Probably all bugs have the same source, thus filing just one issue.
