Debug Tiptap + React 19

This is a minimally reproducible scenario for React 19.1 with Tiptap NodeViews

To reproduce bug

• pnpm install
• pnpm dev
• Navigate to app
• Click button in top right to insert a container Node with 1 child item Node
• Observe the getPos error in prosemirror-view's NodeViewDesc.posBeforeChild on the 2nd render.

App.tsx:59 TypeError: Cannot read properties of undefined (reading 'size')
    at _NodeViewDesc.posBeforeChild (index.js:779:24)
    at ReactNodeView.getPos (index.js:1287:39)
    at Object.getPos (ReactNodeViewRenderer.tsx:84:26)
    at ContainerView (App.tsx:57:52)
    at react-stack-bottom-frame (react-dom-client.development.js:23863:20)
    at renderWithHooks (react-dom-client.development.js:5529:22)

Notes

This bug is only reproducible when causing an immediate re-render of the container Nodeview
