P2P Add-on causes the Visual Form Builder to not save when duplicating sections

Expected Behavior: I should be able to duplicate sections of the form and save it, even with the P2P add-on.

Actual Behavior: It doesn't save and, checking the error logs, generates this error:

Reference node with the name "formId" not found - cannot insert new node.

{

"exception": {

"File": "InsertNode.php",

"Line": 58,

"Message": "Reference node with the name \"formId\" not found - cannot insert new node.",

"Code": 0

}

}

With the P2P add-on active on the website, edit a form using the Visual Form Builder. Duplicate a section then save the form. Saving will result in an error and the form will not be saved.

For forms already made before with duplicate sections, this results in a critical error on the front-end of the form.

High (major issue, but a workaround exists)

Include information about the environment where the bug was encountered:

Device: PC

Browser: Chrome 93

Plugin Version

Core - 3.17.0

P2P - 2.4.3

WordPress Version 6.6.2

PHP Version 8.0

I'm actually not sure how critical it is because this might just be an edge case scenario when someone duplicates a section on a VFB form and the P2P add-on is active.

Moreover, I found a workaround for it. It only happens when you duplicate the blocks. But if you choose a block from the block lists (that creates a section), it doesn't happen.
