✅ Outcome

• Fixed apps/www/src/registry/ui/inline-combobox.tsx to keep the live PointRef itself, then read pointRef.current only when canceling input.
• Added regression coverage in apps/www/src/registry/ui/inline-combobox.spec.tsx that fails on the stale snapshot bug and passes with the fix.
• Updated the registry changelog in content/components/changelog.mdx and regenerated registry output, including apps/www/public/r/inline-combobox.json and apps/www/public/r/components-changelog-docs.json.

⚠️ Caveat

• Browser check skipped. This is a ref-bookkeeping bug, not a visual/UI rendering change.
• Local repo gate was briefly blocked by mixed .bun and .pnpm React installs; pnpm run reinstall cleared that corruption and pnpm check passes now.

🏗️ Design

• Chosen seam: fix the component’s ref ownership in apps/www/src/registry/ui/inline-combobox.tsx.
• Why not quick patch: any version that still copies pointRef.current just rebrands the same stale snapshot bug.
• Why not broader change: the editor PointRef API is already correct; the misuse was local.

🧪 Verified

• bun test apps/www/src/registry/ui/inline-combobox.spec.tsx
• pnpm install
• pnpm --filter www build:registry
• pnpm --filter www typecheck
• pnpm lint:fix
• pnpm check
