When visiting this URL https://pie-production.walgreens.com/ using uTLS with a Chrome parrot the TLS handshake gets corrupted.

When I visit it in my browser (Brave) I get a HTTP 404 (expected) and the TLS handshake gets a Hello Retry Request with a TLS cookie. This is the same in Go as well and in the browser it does another Client Hello with the TLS cookie but in Go it sends a malformed Client Hello with a bugged out cookie.

This seems like a bug, but I'm not sure how to debug this yet as I'm pretty new to this codebase.
How/where does this behavior occur?
