Nesting blocks

[todor0v]

I have modals on my website for which I would like to use blocks. In each modal, you can choose from a number of blocks to use for its content. The problem is that these modals can themselves be used in one of those blocks. For example, a reusable block for list items, each of which can have a modal, and in that modal, you have more list items.

Currently, if I try to use the same block for this, I get an error:

ReferenceError: Cannot access 'modalField' before initialization

My solution is to just create an exact copy of the same block (modalListBlock) instead of listBlock and use that. Is there any better alternative?
