Use of padding should be margin instead

I'm in the process of theming the Category image on the Catalog page and with how the code is structured now the CSS reads:

img.category {
  float:right;
  padding-left:1em;
}

And when I apply a border to that image it looks like so:

The reason the border isn't appearing correctly is due to the "padding-left:1em;". This should instead read "margin-left:1em;". Once changed it looks correct like this:

Can we please get this changed so it is correct in the module? Thanks for all the hard work!
