a11y - Challenge buttons go away in Windows high contrast mode #244
Description
Fully patched Windows 7 Firefox 38.0.5
Toggle Windows high contrast mode on with left-alt+left-shift+printscreen.
Reload page with recaptch and check the not a robot checkbox. The new
challenge, audio and help buttons disappear because they are constructed using
css background images. Background images are used for decoration, not content,
so they are considered disposable, which high contrast mode does to de-clutter
the display. Change to standard img tag sprite maps instead to fix.
