[BUG] window is not defined at _getStackFromErrorObj

[EvgenyWas]

Description/Screenshot
I connected the Application Insights JavaScript SDK to my Nuxt 3 app on both sides - server and client, and in my Application Insights events I see this log with the following message for the tracked exception value:
ReferenceError: window is not defined at _getStackFromErrorObj (/app/.output/server/node_modules/@microsoft/applicationinsights-web/dist/es5/applicationinsights-web.js:6331:22)

And in your code I found this line that causes this issue - link.

I understand it might be happening because I use the Application Insights package for the web and some methods might be executed during SSR, but it's a little bit annoying because this check for the existing window is not correct.

• OS/Browser: windows x64
• SDK Version [e.g. 22]: "@microsoft/applicationinsights-web": "^3.0.2"
• How you initialized the SDK:

const appInsights = new ApplicationInsightsClient({
    config: {
      connectionString,
      enableAutoRouteTracking: true,
      autoTrackPageVisitTime: true,
      enableCorsCorrelation: true,
      enableUnhandledPromiseRejectionTracking: true,
      enableAjaxPerfTracking: true,
    },
  });

Expected behavior
There is no such a log in Application Insights tracked exceptions. The usage should be isomorphic or at least fault-tolerant for such cases.

Additional context
Thanks for your work and I will be glad to update this issue with more information for a speedy solution.

While the code was created to "check" for the existence of window before using it, this is occurring because the runtime is complaining about the non-existence of the "global"

} else if (window && window["opera"] && errorObj[strMessage])

So we will need to change this to use the getWindow() helper which handles this scenario.
