Currently, relative product option value price is calculated ONLY based on price difference between selected and non-selected product option value:

• if priceType is static, difference is [selectedOptionValue.price - nonSelectedOptionValue. price]
• if priceType is dynamic, difference is [selectedOptionValueCPInstance.finalPrice - nonSelectedOptionValueCPInstance.finalPrice]

If options are SKU contributors, the algorithm should also take into account the difference in price between SKUs that defines currently selected and non-selected option values!

Steps to reproduce:

1. Setup a product bundle in Admin UI (for simplicity we can use priceType=static options so no need to create additional products)

• • Create 1 simple product which will represent a product bundle
  • add 1 SKU contributing option with priceType=static (use single select field type, "select from list"  field type is bugged), and add 2 option values
  • define prices for option values (for example value1 = 20 $, value2 = 40$)
  • generate product bundle SKUs for each option value
  • define different prices for each SKU (value1 SKU = 5$, value2 SKU = 10$)

1. In Storefront select the created product bundle

Expected behavior:

Option value relative prices should include a difference in SKU prices. Total price of value1 SKU is  20+5 = 25$, price of value2 SKU is 40=10 = 50$ which means if value 1 option/SKU is selected relative price of value 2 option should be +25$, if value 2 option/SKU is selected relative price of value 1 option should be -25$ etc...

Feel free to add more options, with dynamic priceType and test more complex cases!
