options_background texture shifted by two pixels in Resource Packs screen

When in the resource packs menu, the background texture is shifted to the right by two pixels on the top and bottom of the screen. I've made a resource pack that highlights the problem, which is used in the screenshots below.

Definitely not the sort of groundbreaking discovery worthy of the coveted custom cape (though it IS an 8-year-old bug... dirt cape?), but I'm doing my part to make Minecraft a better place one (or I guess two) pixels at a time.
