Steps to reproduce:

1. Start a 7.2 bundle with the latest fix pack (8)
2. Create a web content
3. Fill the translation for two language title and clear the content field
4. Publish the web content while one of the translation is selected
5. Edit the web content, check the translations
6. One of the translations has the content of the default language but the previously selected language is empty.

Expected behavior: Both translations' web content fields should contain the default language content.

Current behavior: The web content appears in one of the translations but the other is empty.
