Content perspective shows previously made changes after discard them from VE.

Scenario:

1. Start editing document in Content perspective, e.g. add '111' to Title field of Hap news. Don't save it.
2. Open same document in VE and edit same field with new changes: add '222' next to '111'.
3. Discard changes in VE
4. Go to content perspective of the same news document.

Expected: Neither '111' nor '222' saved to edited field of news item.

Current result: Edited field contains '111' value but not '222'. After clicking 'Edit' button again edited field doesn't contain  neither '111' nor '222'
