jails FreeBSD 11.1 to 13.0 what changed in jail interface behavior? jail network dead.

Is there a flag to get the old behavior? Previously whenever I removed and added back an IP address to the jail's interface from the host side, the jail continued working. In fact, for loopback addresses inside of the jail it continued working even if the interface stayed without an address. Since moving to 13.0 the entire network stack seems to go down forever in the jail whenever I remove the IP address from the jail's interface. And I get this kind of errors even for the loopback address:

Code:
telnet: connect to address 127.0.0.1: Network is unreachable

Only a restart of the jail helps.

Could someone please shed some light on this? Is there a flag to get the old behavior? Thank you in advance for your help.
