[BUG] calling trackPageView does not create new traceparent

[Stralos]

Description/Screenshot
When enableAutoRouteTracking is enabled, route changes in SPA result into a new Traceparent header being generated for all outgoing requests

If we disable this property, and call .trackPageView manually, this does not result to a new Traceparent being generated for all ongoing requests

Steps to Reproduce

• OS/Browser: Edge (should behave same on any browser)
• SDK Version [e.g. 22]: 3.3.9
• How you initialized the SDK:

import {
  ApplicationInsights,
  DistributedTracingModes,
  ITelemetryItem,
} from "@microsoft/applicationinsights-web";

const APP_VERSION = import.meta.env.APP_VERSION || "unknown";

function injectAppData(envelope: ITelemetryItem) {
  if (!envelope.data) {
    return;
  }

  envelope.data.appName = "app name";
  envelope.data.appVersion = APP_VERSION;

  envelope.data.origin = window.location.origin;
  envelope.data.href = window.location.href;

  envelope.data.viewportWidth = window.innerWidth;
  envelope.data.viewportHeight = window.innerHeight;
}

export async function getInsights() {
  const appInsights = new ApplicationInsights({
    config: {
      autoTrackPageVisitTime: false,
      connectionString: 'key'
      distributedTracingMode: DistributedTracingModes.W3C,
      enableAutoRouteTracking: false,
      enableCorsCorrelation: true,
      enableUnhandledPromiseRejectionTracking: true,
    },
  });
  appInsights.loadAppInsights();
  appInsights.addTelemetryInitializer(injectAppData);
  appInsights.context.application.ver = APP_VERSION;
  appInsights.trackPageView();

  return appInsights;
}

Expected behavior

• Calling .trackPageView() should update the Traceparent header

Additional context
I can see in this issue there is a discussion about this behaviour, and solutions are presented here

Is this the expected solution to this issue ? If yes, should it be documented somewhere ?

Currently, the same solutions are still recommended #2490 (comment) And we are currently working on the trace api #2647
