Preconditions (*)

1. Magento 2.4.2 - community

Steps to reproduce (*)

1. Create a product: Set product price zero($0.00). Create Customizable Option by dropdown field. Add an option with any price. For example $100.00
2. Create a catalog price rule.(Marketing - Catalog Price Rule) Set apply as percentage of original and set discount amount to 50.00. Save and apply

Expected result (*)

1. On frontend, should apply discount price. And price of that product should show $50.0

Actual result (*)

1. Discount is not applying. Price shows $100.00 when we select that option on frontend.

Note: If we change product price to $0.01 from $0.00, Discount apply on custom option price properly. But when product price is zero($0.00) discount amount is not applying on custom option price as expected. For any other Product Price - There is no issue.
