`Cannot resolve a DOM node from Slate node` uncaught error since Sanity `v4.1.0`

[indeox]

Describe the bug

When a PortableText area has a code type block, and the window is unmounted for whatever reason (switching to another post, or closing the editor pane), Slate throws up an error.

• Changes seem to be saved successfully 👍
• But the error is quite "loud" 😔

To Reproduce

1. Go to a post with a code block on it
2. Make sure the PortableTextEditor is active by clicking on it
3. Switch to a different post OR close the editor pane
4. See error

Expected behavior

No error should be shown
