Steps to Reproduce

I have quite a complex router so I recreated a small part of it here with repro steps in the readme: https://github.com/tirli/repro-sentry-react-router

I'm pretty sure several nested SentryRoutes are to blame here but I cannot rewrite my usage of the router :( Also, I've seen a lot of similar issues that are blaming the wrong order of sentry init and router usage so I checked this case and I feel like it's not the problem here

Expected Result

Actual Result
