Strange, I cannot reproduce. And reading the code, I don't understand
why it behaves like this.

- "&" calls dired-do-async-shell-command.

- There, we see the call of

   (let ((files (dired-get-marked-files t current-prefix-arg nil nil t)))

- The first argument of this function, "t" (LOCALP), means to return a
  list of relative file names. ("1.txt") in this case.

- Therefore, the shell command should be "cat 1.txt &". This should work
  (and does in my test).

Do you have a chance to debug dired-do-async-shell-command? What does
the call of dired-get-marked-files return?

Alternatively, is there a robust scenario to reproduce the problem?
