Issue description:

When using ctrl+x or "Cut" in editor, content gets removed but it cannot be pasted, instead we get "<!-- wp:lzb-constructor/main /-->" on paste.

Lazy Blocks Version:

2.3.1

WordPress Version:

5.7.1

Also, would be neat if we could restrict which Inner Blocks can be added inside Inner Block control. Is this something that could be filtered maybe?
Other than that, repeater in repeater is most wanted, I saw that last discussion about it was 2 years ago...any news on that?

I really enjoy using Lazy Blocks!
