Original Pull Request

#18225

Description

Issue is connected to the custom option price conversion based on base currency configured on default level, but not on website level (Magento allows to configure different base currency on website level according to documentation).

It's reproduced on the following Magento setup with multi-currency configuration:

1. There are 2 websites configured: US and CA (or another one).
2. Base Currency is configured in the next way: default level - USD; CA - CAD.
3. And if you try to update product with custom options (with non zero price) on CA website level, for example, you need just to change product price, every time you save the product, custom options price will be converted according to USD/CAD currency rate.

Fixed Issues (if relevant)

No related issues found.

Manual testing scenarios

Steps to reproduce

1. Create 2 websites on Magento: US website and CA website.
2. Set up Base Currency to USD (or any other) on default scope.
3. Set up Base Currency to CAD on CA website scope.
4. Create product with custom options and set up non zero price for option value.
5. Save the product.
6. Change configuration scope on CA website.
7. Save product.

Expected result
Custom option value price is not changed, because no actual changes were done.

Actual result
Custom option value price is updated according to USD/CAD currency rate.
