Steps to reproduce:

When I run the VSCode debugger against MS Edge Dev it sets navigator.webdriver to true. This is not supposed to happen. Doesn't happen if I run against Chrome.

Debugger configuration:

    {
      "name": "Edge with Webpack Debugging Server",
      "type": "edge",
      "version": "dev",
      "request": "launch",
      "url": "http://localhost:3000",
      "webRoot": "${workspaceRoot}/src",
      "userDataDir": "${workspaceRoot}/.chrome",
      // "trace": true,
      "sourceMaps": true,
      "smartStep": true,
      "skipFiles": [
        "${workspaceFolder}/src/node_modules/tslib/*.js",
      ],
      "sourceMapPathOverrides": {
        "webpack:///./src/*": "${webRoot}/*"
      },
      "runtimeArgs": [
        "--disable-session-crashed-bubble",
        "--disable-infobars"
      ],
      "internalConsoleOptions": "openOnSessionStart"
    },
