Browser already running from configured userDataDir

[aeschli]

Ubuntu 20.03 with Chromium installed (not Chrome)

• create a launch config

      {
          "type": "pwa-chrome",
          "request": "launch",
          "name": "Launch Chrome against localhost",
          "url": "http://localhost:3000",
          "webRoot": "${workspaceFolder}",
          "userDataDir": "${workspaceFolder}/.vscode/vscode-chrome-debug-userdatadir"
      }

• Chromium browser comes up
• shut down VS Code, including the browser. Check the system monitor, no vs code or chromium processes running
• open VS Code again, launch the launch config
• dialog shows.

I'm guessing when vscode is closed, it kills the child Chromium process ungracefully. This dialog is a result of checking for the presence of Chrome's lockfile in the browser's user data dir. It can be safely bypassed if you know that no browser is running.
