Ivy: Non-prefix matches break TAB

[PythonNut]

1. emacs24.5 -Q
2. M-: (setq ivy-re-builders-alist '((t . ivy--regex-fuzzy))) RET
3. C-x C-f
4. Type a non-prefix match.
5. TAB

Should produce:

Can't reproduce. Everything seems to work fine.

Can you give me a copy of the candidate list? Looking at ivy--all-candidates should be enough. Also give me your non-prefix input.

[PythonNut]

@abo-abo try the following:

(ivy-with '(ivy-read "test" '("aaaabbbbbaaaa" "aababa" "babab"))
          "aba C-i C-m")

[abo-abo]

Works fine for me: TAB extends the input to abab without changing selection. C-m then selects the first candidate.

Although with ivy--regex-fuzzy a different candidate is selected, because of the sorting.

• emacs-24.5 -Q

(setq ivy-re-builders-alist '((t . ivy--regex-fuzzy)))
(package-initialize)
(ivy-mode +1)
(ivy-read "test" '("aaaabbbbbaaaa" "aababa" "babab"))

• M-x eval-buffer RET
• aba TAB

Should do it.

[abo-abo]

OK, I can reproduce now. It's not reproducible on Emacs 25, which I normally use.

Thanks.
