[PRO]: Unique-ID Regenerates If Node Has No Content

Affected Packages

@tiptap-pro/extension-unique-id, @tiptap-react

Version(s)

2.10.11

Description of the Bug

When you have nodes with no content, the unique-id is regenerated.

Example 1: Headings

Editor options:

Heading.configure({
  levels: [1, 2, 3, 4, 5],
}),
UniqueID.configure({
  types: ['heading']
}),

Parse and render HTML content:

const content = '<title-node></title-node><h1 data-id="a70661d9-cd0d-4119-941f-a16b6f788397"></h1><h1 data-id="0e6d8ef0-4961-49cf-9461-c0f339579325"></h1>'

editor.commands.setContent(content)
console.log(editor.getHTML());

The console.log statement returns:

<h1 data-id="a70661d9-cd0d-4119-941f-a16b6f788397">
</h1><h1 data-id="e6443c31-c5d0-40f3-98a7-d4e2a5699fc6"></h1>

As you can see the second heading doesn't preserve it's id, but regenerates a new one.

Example 2: Custom extension

Test Extension (simply renders the id):

import { Node } from '@tiptap/core';
import { NodeViewWrapper, ReactNodeViewRenderer } from '@tiptap/react';

const Component = ({ node }: any) => (
  <NodeViewWrapper as="span">
    {node.attrs.id}
  </NodeViewWrapper>
)

const Test = Node.create({
  name: 'test',
  inline: false,
  group: 'block',
  atom: true,

  renderHTML({ HTMLAttributes }) {
    return ['test', HTMLAttributes];
  },

  parseHTML() {
    return [
      {
        tag: 'test',
      },
    ];
  },

  addNodeView() {
    return ReactNodeViewRenderer(Component);
  },
})

export default Test;

Setting the content:

const content = '<test data-id="a70661d9-cd0d-4119-941f-a16b6f788397"></test ><test data-id="0e6d8ef0-4961-49cf-9461-c0f339579325"></test >'
editor.commands.setContent(content)

Rendered content:

Again the second id is not preserved.

Important note: This bug only occurs when the content of the node is empty and only then to the following node. So we have headings with content everything works as intended. This is particularly painful when building a custom node that doesn't have any content.

I tried to fix the package code myself. However, I found out that the code is obfuscated. Thus, I am at your mercy of resolving this issue.

Thank you in advance for your support!!

Reading through the code it looks like this was intentional though I cannot understand why. Would need @bdbch to shed light on it
