SDK Setup

Sentry.init({
      replaysSessionSampleRate: 1.0,
      replaysOnErrorSampleRate: 1.0,
      environment: "production",
      integrations: [
        new Sentry.Replay({
          maskAllText: false,
          blockAllMedia: false,
        }),
      ],
    });

Steps to Reproduce

Run through the webapp and record a replay. The replay is then sent to Sentry.io with user's IP, email and name, but any extra key pair is not being saved.

Follows snippet for setUser

Sentry.setUser(
      {
        username: 'My name',
        email: '[email protected]',
        agency_name: 'My company name'
      }
    )

Expected Result

I expect to receive the agency_name and this be recorded anywhere on Sentry Replay (probably under TAGS)

Actual Result

user.ip, user.email and user.username displays on TAGS tab on Replay. The agency_name doesn't show anywhere.
