It depends on the implementation of the DNS rebinding protection.
I have just checked, and my pfSense firewall (which claims to block DNS rebinding) blocks local addresses from resolving through xip.io (tested with loopback and several RFC1918. All blocked, regardless of whether they match the subnet in use). External addresses (e.g. 1.1.1.1.xip.io) resolve fine.
