[x] I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
[x] I have reviewed the documentation https://docs.sentry.io/

Reproduction Example/SDK Setup

Sentry.init({
  dsn: "_MY_DSN_",
  integrations: [
    Sentry.browserTracingIntegration(),
    Sentry.replayIntegration(),
  ],
  tracesSampleRate: 0.1, 
  replaysSessionSampleRate: 0.1, 
  replaysOnErrorSampleRate: 0.3, 
});

Steps to Reproduce

Not available.

Expected Result

Replay reproduction shows user's page loads when he/she navigates through pages in the application.

Actual Result

Pageloads are not displayed on replays. The mouse movements, clicks and breadcrumbs point to the user navigating and using other pages, but the replay shows only the landing page of the application.

There were no changes on the application side when the issue started, issue also affected v7.100.0 of the SDK.

Original request and links to examples are available in the linked Jira issue (contains PII).
