expires larger than timeout causes error

I have an IPv4 set with timeout 2d, but update its elements to 4d when
a rule matches. It was fine until kernel is updated to 6.12.6 or 6.12.7.
E.g. the following snippet gives an error when importing:

table inet blocker {
        set spam_ips {
                type ipv4_addr
                size 65535
                flags dynamic,timeout
                timeout 2d
                elements = { 1.2.3.4 expires 3d }
        }
}

a.nft:7:16-22: Error: Could not process rule: Numerical result out of range
                elements = { 1.2.3.4 expires 3d }
                             ^^^^^^^

kernel 6.10.6 worked just fine. nftables cli v1.1.1.

Despite I can't import the set, existing elements can still be updated
to timeout more that 2d.

A new bug? Or a new limitation?
