[🐞] v2: ownerDocument is null during deserialization

[thejackshelton]

Which component is affected?

Qwik Runtime

Describe the bug

When clicking the "Next" button in a user created pagination component, a runtime error occurs during text node inflation:

Root Cause

The error occurs in Qwik's vnode_ensureTextInflated function when trying to access parentNode.ownerDocument during DOM deserialization. The ownerDocument property is null when the pagination state changes.

Environment

• Qwik v2.0.0-beta.7
• Package Manager: pnpm
• SSR mode (pnpm dev runs with --mode ssr)
• Pagination component with conditional rendering and text content

Core API's used:

• Pagination uses context
• PaginationItem with conditional rendering based on computed signals
• PaginationNext that updates the selectedPage signal on click
• Text content within Slot components that triggers text node inflation
• A render component primitive for composition

Reproduction

https://github.com/thejackshelton/v2-owner-document-repro

Steps to reproduce

1. Install dependencies: pnpm install
2. Start development server: pnpm dev (SSR mode)
3. Load the page with pagination component
4. Click the "Next" button
5. Error occurs during DOM text node inflation/deserialization

Technical Details

The error happens in this code path:

const doc = parentNode.ownerDocument; // parentNode.ownerDocument is null
