When a node is translatable, it's possible you have two edit screens open from the same node, but in a different language.
The tempstore has no clue about the language, so hitting preview might overwrite the node stored in tempstore.

- Open two languages for the same node in two tabs
- http://localhost/en/node/1/edit
- http://localhost/fr/node/1/edit
- press preview on the french one, then preview in the english one
- Press back to editing in the french one, you are now editing in English

Borderline critical as there is data loss involved here.

Nice find, the patch looks pretty simple, but we'll need tests for it.
