I'd like to test the following patch applied by the community. As seen here, https://github.com/magento/magento2/pull/13359/files.
Since I've always installed Magento via composer, is there an easy way to test this patch against a Magento 2.2.2 install where the code exists in the Vendor directory? In Magento 1, I could see testing this in app/code/local/Mage, but since that no longer exists what does everyone recommend as a solution?
Thanks!
