Must the Gateway Load Balancer Frontend IP be in its own subnet?

hi!
Recently our deployments with Azure Gateway Load Balancers stopped forwarding traffic back to their chained public load balancers. To solve the issue, we put the GWLB frontend IPs in dedicated subnets beside our NVAs. Is this necessary? Has anything changed to cause this behavior?
