Steps to reproduce on latest master:

1) TS Setup:

config.no_cache=1
page = PAGE
page.1 = TEXT
page.1.data = page:title
page.1.wrap = <h1>|</h1>
page.10 < styles.content.get

2) Create a custom workspace
3) Create a page in LIVE worskpace
4) Create a content element, put a headline (remember its ID e.g. 443)
5) Go to custom workspace and click on page created at point 3)
6) You will find in page module that the content element has been duplicated: you will have two content elements, with the same headline and different ids (id=443 and id=444)
