(Under Fedora 26 and X, also with master,) to reproduce:
- "emacs -Q",
- C-h i for *info* buffer,
- g for "Go to node:",
- (does-not-exist) RET.
Result:
- Mini buffer says: "Info file does-not-exist does not
exist",
- then switches back to "Go to node: (does-not-exist)",
- but cursor is put in *info* buffer, thus requiring to C-x
o to reenter mini buffer to correct (or abort).
Expected result:
- The cursor should be in the mini buffer, not in *info*.

Utterly weird. I've tried to debug this, and the error is in
(Info-read-node-name "Go to node: ")
If you type "foo", then point does not move to the *info* buffer. If
you type "(foo)", then point does move to the *info* buffer.
It seems like it's this code
(lambda (string pred action)
(complete-with-action
action
(Info-build-node-completions (Info-find-file file1))
string pred))
that somehow (when `Info-find-file' raises a user-error pops to the
*info* buffer... somehow...

OK, one step further. The following pops to the *info* buffer:
(completion-table-with-context "(foo)" (lambda (string pred action) (complete-with-action action (Info-build-node-completions (Info-find-file "foo")))) nil nil nil)

OK, here's the bug:
;; If there is no previous Info file, go to the directory.
(unless Info-current-file
(Info-directory))
(user-error "Info file %s does not exist" filename)))
Info-current-file is nil here, so it helpfully pops us back to the
*info* buffer before displaying the error. I'm not sure what the right
fix here is...

I've now pushed a fix in Emacs 27.1.
