Image disappears in high contrast mode.

[beefancohen]

The problem
Images disappear in high contrast mode on Windows OS browsers because high contrast mode strips away background images and the accessibility image has opacity:0.

How to reproduce

1. Use a windows laptop and turn on high contrast mode.
2. Navigate to a user profile on mobile.twitter.com in Firefox, for example.
3. Notice the profile image is not visible.

Expected behavior
The image is accessible.

Other information
Windows has a -ms-high-contrast media query that can be used to detect high contrast mode, otherwise I'm unsure of detection mechanisms.

Apparently high contrast mode is meant to support background images - https://blogs.windows.com/msedgedev/2016/04/20/building-a-more-accessible-web-platform/

I believe that's just for edge?
