There is no link between blocks of different languages.

• If an author edits, moves, splits or joins blocks in one language this has no impact on the other languages.
• Each language can have a different number of blocks. Sometimes a translation is rather a "localization". You might have a locale-specific ad or teaser block in between text.

AC:

• Create UI test for those operations above

• Expect change in one language will not raise any impact to the others
