Found a bug when editing related product rules with dates start: 2019-05-15 to 2108-05-15, when you edit the rule magento return a message for: "End Date must follow Start Date."
The problem seems to be in the "to" input field because the date is rendered like "5/15/08" instead of "5/15/2108" (better if the date is "2108-05-15").
I believe that Magento understand that the date is from 19xx instead of 20xx century.
Please fix for future uses, it's really anoying to edit 100 rules with the same bug.
