Bug summary
When creating a simple block inside a slot in an area, across variant cultures, the "first" variant will succed, and the second "greyed" out block will create a duplicate.
Specifics

Steps to reproduce
Create a block grid on an umbraco site with 2 or more languages, on a document type that allows vary by culture.
The block grid should be invariant, and should have an invariant element type for the area and a variant element type to put inside the area.
If you create the first variant (ie. English or something) and fill out the area, then when it comes to fill in the other variant, which now should have a greyed out block, creating it will result in a duplicate being added below the area as well.
They must also have duplicate keys, because deleting the duplicate, will also delete the original on all variants.
Expected result / actual result
I'd expect the blocks to only be created inside the area slots without duplicates
