In field group editor deleting a repeater doesn't hide the corresponding block

[a-barbieri]

Issue

In field group editor you can delete a repeater. The UX is not consistent though: deleting a repeater field immediately remove the field instance, but the block with the children fields remains there. It disappear only once you refresh the page.

Expected behavior

I'd expect to see the children block disappear as well.

How to reproduce the issue

1. create a repeater in a field group editor
2. save
3. delete the repeater

The repeater disappear but the children block remains.
