Non unique IDs when duplicating block containing Lexical block

[bratvanov]

Describe the Bug

Somewhat related to #8784 / #8790, which was already fixed for nested arrays/nested regular blocks (CC: @r1tsuu)

However, when a Lexical block is nested into a regular block, and the outer regular block is duplicated, the inner Lexical block will still get the same ID as the original Lexical block.

Reproduction Steps

1. Have a blocks field containing a richText field containing a custom Lexical block.
2. Duplicate the outer block via the admin UI context (...) menu.
3. The new block's nested Lexical block has the same ID as the original.

{
    "blockType": "sections",
    "content": {
        "root": {
            "children": [
            {
                "type": "block",
                "fields": {
                    "id": "67c0658ae002eb8c202022bf",
                    "blockType": "simpleBlock"
                }
            }
            ],
        }
    },
    "id": "67c0658618c45a82f4b65509"
},
{
    "blockType": "sections",
    "content": {
        "root": {
            "children": [
            {
                "type": "block",
                "fields": {
                    "id": "67c0658ae002eb8c202022bf",
                    "blockType": "simpleBlock"
                }
            }
            ],
        }
    },
    "id": "67c0658c18c45a82f4b6550e"
}

Hey @bratvanov

I'm no longer able to reproduce this with latest - I think it was fixed in #11579 thanks to @jacobsfletch! Want to confirm on your end?

Edit: I was incorrect, this is reproducible, just have to add a nested block in the editor itself and then duplicate.
