Conflict between v-once and ref

[schoonc]

Version

2.5.2

Reproduction link

https://jsfiddle.net/pb32s2p3/6/

Steps to reproduce

Open console (ctrl+shift+i in chrome, for example).

What is expected?

Output in console:

<div></div>
<div></div>

What is actually happening?

Output in console:

<div></div>
undefined

---

If remove 'v-once' or change vue version to 2.4.4 (in 2.5.1 and 2.5.0 bug remains) problem disappears.

Thanks.
