Product images gets removed from "Images And Videos" after validation alert.

[candia]

When adding a new product with an image, if a validation error occurs when trying to save the prodcut, the images gets removed from the "Images And Videos" section. If you fix the validation conflict and try to save the product again, an error will occur with "The file "/home/user/www/pub/media/tmp/catalog/product/o/r/pic.png" doesn't exist or not a file"

Preconditions

1. Magento CE 2.1.2
2. New Product

Steps to reproduce

1. Add new product
2. Add image to product
3. Force a validation error by using an already used URL Key for the product

Expected result

Magento should remember the image that was added before validation occurred and save the product with the image.

1. Create product with image

Actual result

1. The file "/home/user/www/pub/media/tmp/catalog/product/o/r/pic.png" doesn't exist or not a file

I checked the pub/media/tmp and the image was added to the folder, however once I click save and validation is triggered the image gets removed from the pub/media/tmp.
