Issue

The target rule for Related Products does not work when "is one of" condition is used for Products to Display in Magento Admin.

Note: This patch does not fix existing target rules. You must re-create existing target rules.

Steps to reproduce:

1. Create New Attribute (Example: Test_Attr).
   • Set Catalog Input Type for Store Owner = Text.
   • In Storefront Properties, set Use for Promo Rule Conditions = Yes.
2. Create New Attribute Set (Example: Test_Set).
3. Add the New Attribute to the New Attribute Set (Example: Add "Test_Attr" attribute to the "Test_Set" attribute set).
4. Create 3 products. For the Example, they are set like this:
   
   • Product1, Test_Attr = MAGT2NA_Test3
   • Product2, Test_Attr = 24-MB02
   • Product3, Test_Attr = 701644329389M
5. Create target Rule (Marketing > Related Product Rules and click the Add Rule button.) with settings:
   • Apply To = Related Products
   • Products to Match
     • Set the New Attribute you created in Step 1 above to be the Product1's attribute (Example: Test_Attr = MAGT2NA_Test3).
   • Products to Display = The attributes of the other 2 products (Example: 24-MB02 and 701644329389M attributes).
6. Save the Rule.
7. Run a reindex, if needed.
8. Clear cache.
9. Open Product1 on the frontend.

Expected result:

The related products are present as expected.

Actual result:

The related products are missing.
