[BUG] Custom properties added with addTelemetryInitializer are ignored for first PageVisitTime track event

[Nosfit]

Description/Screenshot When I set autoTrackPageVisitTime to true in the ApplicationInsights configuration, the first payload for PageVisitTime does not contain any custom parameters that I added using the addTelemetryInitialiser method.

Steps to Reproduce init telemetry with custom properties:

const appInsights = new ApplicationInsights({
      config: {
        appId: 'test-bug-report',
        connectionString: this.connectionString,
        autoTrackPageVisitTime: true,
      },
    });
    appInsights.loadAppInsights();
    appInsights.trackPageView();
    appInsights.addTelemetryInitializer(this.enrichTelemetry);

    ///

   enrichTelemetry = (item: ITelemetryItem): void => {
      if (item.tags == null) {
        item.tags = [];
      }
      item.tags['ai.cloud.role'] = 'test-bug-report-roleName';
      item.tags['ai.cloud.roleInstance'] = 'test-bug-report-roleInstance';
    };

then visit your application and see on first track request in network section.

Additional context Add any other context about the problem here.

Yes, this is because you are adding the telemetry initializer "AFTER" you are triggering the page view

flip the order of these 2 functions

    appInsights.trackPageView();
    appInsights.addTelemetryInitializer(this.enrichTelemetry);

to

    appInsights.addTelemetryInitializer(this.enrichTelemetry);
    appInsights.trackPageView();

Thanks. That helps
