Title: Fix for #3482: radio boxes "not working" in master ("checked" is cleared inappropriately)

I tested this fix on the newest master and it works well for me. Without this fix all my radiobox validation code, etc fails, because things like .filter(":checked") yield a blank list (the only time when they don't is when the form is first loaded and hasn't been changed yet, and the first radio button option is selected)
