And yet, we can still see it on almost any block explorer that you check. There are more and more nodes running with much larger limits than the default, so you can no longer rely on transactions being dropped at all.
I suppose blockexplorers connect to more nodes than any other default node or they run their own nodes with increased limits. This is why they will likely show you transactions as unconfirmed even if they've been dropped from the majority of the nodes.
I imported OP's address into Electrum (watch-only) and tryed different servers (about 10 servers). Only one of them has the transaction in its mempool and showed the transaction as unconfirmed. The status changed to
local when connecting to other servers.
