Preconditions:

Content Type with ezmatrix.

Steps:

1. Go to Content/Content structure and click Create
2. Select CT from preconditions
3. Add some new rows in ezmatrix field and leave them empty
4. Click Publish

Actual result:

Preview displays that ezmatrix field is empty - OK. But When I go back to edit mode, there is only one empty row.

Expected result:

If we allow user to add and publish empty rows, maybe we should keep them when he's going back to edit mode?
