ok, the reproducer:
1.
#nft delete table foo
#nft add table foo
#nft list tables
#nft list table foo
#nft add chain foo bar
#nft add chain foo baz
#nft add chain foo bok
#nft list table foo

2. #nft -f panic.rules
------panic.rules-------
add rule foo bar ip saddr 127.0.0.1 accept
add rule foo bar ip saddr {192.168.1.2, 192.168.2.3} jump baz
add rule foo bar ip saddr {192.168.1.2, 192.168.2.3} jump bok

add rule foo baz ip saddr {192.168.1.2, 192.168.2.3} jump bok
add rule foo bok ip saddr {192.168.1.2, 192.168.2.3} jump baz

delete table foo
-------end-----------
