Steps to reproduce

No additional steps necessary.

What is expected?

The object passed to defineExpose should remain a reactive object, and not marked as raw.

What is actually happening?

The object is being marked as raw and losing its reactivity.

System Info

Any additional comments?

I believe has behaviour has always been present but has only become an issue in 3.5.14, caused by #12824 .

If this behaviour is intended, it's not mentioned in the defineExpose documentation that reactive objects should not be used.
