YJS Remote Updates Clear Content After Comment Operations

[Adah35]

Describe the bug
When using BlockNote with YJS collaboration and comments enabled, adding comments triggers YJS remote updates that unexpectedly clear block content, resulting in data loss. so when the block gets cleared it triggers the listeners on the server side which tries to save the empty blocks and this replaces the original content,

Environment
Socket.IO Provider: y-socket.io

To Reproduce
Minimal Reproduction

BlockNote editor with YJS collaboration
Comment system enabled
Any text content
Attempt to add a comment to selected text
Monitor editor.onChange() to observe the content clearing

Actual Behavior
When a comment is added, the following occurs:

{
  "type": "update",
  "block": {
    "id": "7e0254be-ecf9-4eb9-b782-f9e9594657ca",
    "type": "paragraph",
    "content": [],  // ❌ Content is cleared!
    "children": []
  },
  "prevBlock": {
    "content": [
      {
        "type": "text",
        "text": "code  ",
        "styles": {}
      }
    ]
  },

```  "source": { "type": "yjs-remote" }  // ❌ Remote update clears content
}


**Misc**

- Node version: 20
- Package manager: npm
- Browser: chrome browser

Hmm, could you double check whether all remotes run the same version of your editor? (perhaps there are some developer tabs open which still run a version without comments enabled?)

exactly, i will update you soon

Edit: found the issue, was using ServerBlockNoteEditor on the server side which did not recognize the incoming marks or even custom inline content or blocks, so i realized i had to pass the same schema to ServerBlockNoteEditor.create() similar to what was going on in the frontend
