name="a" ondblclick="this.checked = false"

if you go through for each item and add ^^ that coding after the

type="radio"
to this


<input id="1-advanced-black" name="itemlist[1][]" type="radio" value="51" checked="checked">


it'd look like this
<input id="1-advanced-black" name="itemlist[1][]" type="radio" name="a" ondblclick="this.checked = false" Clickvalue="51" checked="checked">

you'll be able to Double Click and Deselect Items you currently have up there.
quick fix for the issue until the New Design drops...

don't believe me then check my emcee
