Well, based on your tcpdump output, it looks like your rules were
rejecting unrelated packets, or tcp/443 packets. It's hard to be sure
since the ICMP was the first packet, so you didn't show the packet it
was actually replying to.
The ICMP traffic is a result of rejecting rather than dropping that
traffic. That is, I think you're looking at the problem wrong. The
ICMP traffic is simply the result of a choice you made. Are you
dropping type 3 in the output chain?
