Can we set reverse SSH tunnel back to localhost when debugging a job?

We are running Cypress end-to-end tests during a job, and it would be very nice to see what the UI is doing. On other services (like Docker containers, Cloud9) we just use reverse SSH proxy tunnel when connecting:

ssh -R 6022:localhost:22 -p

But with Circle, we are just getting an error during connection

Warning: remote port forwarding failed for listen port 6022

Is there something we could do here? We would love to use the reverse tunnel to forward X11 traffic back to local display to debug end-to-end tests.
