Left floated images in panopoly content list not floating anymore

I don't know if this is left over from radix 2.x or not, but radix is removing the floats, etc. that are used to float images left and add a margin to the content next to the image. I wasn't sure if there is a bootstrap reason for that or not. Here's a screenie and the css I've identified.

/* line 9, ../../extensions/compass_radix/stylesheets/compass_radix/_node.scss */
.field img.panopoly-image-full,
.field img.panopoly-image-half,
.field img.panopoly-image-quarter {
  max-width: 100%;
  width: auto;
  height: auto;
  float: none;
  margin: 0;
}
