Reproduction Example/SDK Setup

Sentry.init({
  dsn: "__MY_DSN__",
  integrations: [
    Sentry.reactRouterV5BrowserTracingIntegration({ history, heartbeatInterval:8000 }),
    Sentry.replayIntegration({
      maskAllText: false,
      _experiments:{
        recordCrossOriginIframes: true
      }
    }),
    Sentry.feedbackIntegration({
      // Additional SDK configuration goes in here, for example:
      colorScheme: "system",
      includeReplay: true
    }),
  ],
  replaysOnErrorSampleRate: 1.0,
  sendDefaultPii: true,
  });

Steps to Reproduce

1. Open the page with the feedback widget.
2. Do something on the page for 30s or more
3. Open the widget.
4. Wait for some time before sending the feedback

Expected Result

The replay will contain 30s before the feedback widget is opened as mentioned here:

First, make sure that the Session Replay integration is configured correctly and that replaysOnErrorSampleRate is greater than 0. When this is done, the Replay SDK will buffer up to 30 seconds of the user's session until the user opens the User Feedback widget.

Actual Result

The replays start with the widget already opened.
