Scope

What's changed:

• Defer setting readOnly via await nextTick() so it fires after the value watcher's render() when both props change in the same tick

Potential Risks / Drawbacks

• If the root cause is a different one than the DOM updates, nextTick might not be the best solution.

Tested Scenarios

• Opening items with a block editor in the item view and in the relational drawer and verifying the content appears
• Throttled network speed

Review Notes / Questions

• Without the fix, the disabled watcher sets the editor to disabled before the value watcher starts render(), causing EditorJS to silently drop content
