Subject

Composer (Compose page) in admin panel when editing page blocks.

Steps to reproduce

1. Create 6 blocks (names: from 1 to 6)
   
2. Remove first 3 blocks (from top of the list - blocks from 1 to 3)
   
3. Create new block - name it 7
   
4. Refresh page
   

So this is how it looks in database:

They new block (name 7) has incorrect position: 4 - the same as the block with name 4.

I think front-end is sending incorrect position to back-end - it took it from it:

Expected results

Last created block should be last.

Actual results

Last created block is 2nd.

I'm seeing this as an feature more than a bug. You should always drag and drop the newly created block to it's right place so that the position is updated properly.

Pull requests are welcome if you think this is something that should be fixed.
