This is by design. It is due to the RST being generated at different
points within the network stack.
When the REJECT rule creates the RST, the SYN is immediately dropped,
and so there is no existing established conntrack for the RST.
When the TCP layer creates the RST, the SYN has already passed through
all of netfilter, the conntrack is created, and so the RST can use it.
