Example URL:
www.mcmaster.com

Steps to reproduce the problem:
1. load www.mcmaster.com
2. notice entire section under "Fastening & Joining" is missing images
3. notice section for "Pipe, Tubing, Hose & Fittings" image loads fine

What is the expected behavior?
Images should display for first section.  There are other sections on the home page that are also impacted, while other sections show up fine.  It works fine in Chrome 54 on Windows as well as Chrome on iOS and other browsers we've tested.

What went wrong?
The images are sub-sections of a large sprite image set.  It seems the larger sized sprites are failing to be displayed.  This seems to have started with Chrome 54+.  If you select the "Request desktop site" checkbox the images  show up again.  I haven't been able to find any difference in the request/response besides the UserAgent string, so I'm not sure what the browser is doing differently with the images it's getting back.

Does it occur on multiple sites: N/A
