Could you pls check that your checkout is recent? It must contain

--8<---------------cut here---------------start------------->8---
~/src/emacs-26> git log
commit 646e56e150ca08978d6ce736b12867b4958a0cd8 (HEAD -> emacs-26,

    Fix Bug#28959
    
    * lisp/net/tramp.el (tramp-handle-find-backup-file-name):
    Use `tramp-tramp-file-p' rather than `tramp-file-name-p'.  Add
    hop to backup file name.  (Bug#28959)
--8<---------------cut here---------------end--------------->8---

Furthermore, you might run

--8<---------------cut here---------------start------------->8---
~/src/emacs-26> make -C test tramp-tests
--8<---------------cut here---------------end--------------->8---

There are several Tramp tests; the most interesting is

--8<---------------cut here---------------start------------->8---
   passed  43/58  tramp-test34-find-backup-file-name
--8<---------------cut here---------------end--------------->8---

Do you see this?
