This doesn't sound like an error. recentf does what you tell it to
do. After step 3, there is a buffer with the remote file name
"/ssh:localhost#2222:~/a.txt". recentf stores also remote file names,
according to `recentf-keep-default-predicate':
--8<---------------cut here---------------start------------->8---
(cond
((file-remote-p file nil t) (file-readable-p file))
((file-remote-p file))
((file-readable-p file))))
--8<---------------cut here---------------end--------------->8---
The problem seems to be rather ido. Could you pls check bug#24980? It
sounds similar to your problem, and it was solved in Emacs 26.1. Btw,
which Emacs version are you running?
