The background images on my site do not render correctly in Firefox Quantum. There are three PNG images specified on the <body> tag: the positions for each are left, right, and center respectively. The sizes for each are contain, contain, and cover respectively. None of the images render in Firefox unless I disable the "background-size" property completely. They also do not render if "background-size: 100%" is specified, but they do render if I provide a pixel value.

These images render perfectly fine in Chrome, Edge, and IE 11, but not in FF Quantum (57.0.2, Win10 x64).

They may render now in the others, does not mean in the future. Firefox is taking code a little to literately at the moment. Not sure of the fixes for it. But do know that anything that passes W3C - Who make the rules for web code should run if corrected.
