[🐞] Tabs & Inline components: Only primitive and object literals can be serialized

Which package is affected?

Headless Kit

Describe the bug

When putting items inside the tabs, we get an error from Qwik that only primitive and object literals can be serialized.

The reproduction below, is putting a simple icon in the tabs, and it breaks.

This is caused by the Icon being an inline component, if we wrap it in component$ it works fine.

Additional Information

No response

Start with the linked tabs reproduction: install dependencies with pnpm i, run pnpm dev, and reproduce the error by placing an inline icon in a tab item. Trace how Headless Kit tabs serialize their items and compare the behavior with the component$ wrapper. Done means inline icons work without triggering Qwik's serialization error.
