For whatever reason, the most simplest of styling fails to work at this point. FF31.0.1 works fine, Chrome works fine, IE11 works fine, but FF29.0.1 refuses to acknowledge this simple style.
See this for example:

Next to the larger images, there should be smaller sprites next to them. People are reporting cases like this: https://i.stack.imgur.com/UQCWY.png
The <td>
that contains both images is styled with position: relative;
whilst the second image is a position: absolute; bottom: 0; right: 0;
. Why does this not work?
