Describe the bug
When opened by default, the assembly option won't save the information in the orderForm.

To Reproduce

1. Have a product with customization enabled
2. Set the prop initiallyOpened and ensure that it's rendering open.
3. Add a custom text or option according to the customization that you've set.

Expected behavior
Expected to value/option to persist to the checkout.

When I go to the checkout page:

Additional context
Ps: The Bug also occurs if the customization is a text input
