Description

The covers block are not sorted correctly when the "Order" option is modified.
 

How to reproduce?

1. Create a new Page and insert an Action Covers Block.
2. Change the "Order" to 1 of the the first Item. You should navigate to "Quick Edit".
3. Go back to the page and you'll see that the order has not been changed.
