Setting the default values for a CHECKLIST interface var

I'm trying to set the default values for an html Form CHECKLIST interface var. Ive been setting the var to a list of possible values in the Forms Initialize() proc, however, I'm having trouble when the user unchecks all of the boxes. Rather than being set to null, or an empty list, the variable is being left as what I set it to in Form/Initialize().

As long as one of the boxes is checked, everything works fine, but if all of them are unchecked, I get back the previous list. Is there some other way to set these default values, is this a bug, or I am just mangling the heck out of this?

Heres a quick test:
Form
    test
        var
            options
            options_interface = CHECKLIST
            options_values = list("Option_1", "Option_2")

        Initialize()
            ..()
            var/mob/M = usr
            var/templist[0]
            if(M.option1)
                templist += "Option_1"
            if(M.option2)
                templist += "Option_2"
            options = templist


        ProcessForm()
            var/mob/M = usr
            var/list/templist = options
            M.option1 = FALSE
            M.option2 = FALSE
            if(templist)
                if(templist.Find("Option_1"))
                    M.option1 = TRUE
                if(templist.Find("Option_2"))
                    M.option2 = TRUE
            M << browse(null)

mob
    var
        option1 = FALSE
        option2 = FALSE

    verb
        Show_Options()
            src << "Option 1: [option1], Option 2: [option2]"
        Set_Options()
            var/Form/test/T = new()
            T.DisplayForm(src)

Don't use var_values.

I can't remember exactly, but I think it's something like var_option1, var_option2. That's not it, but someone else will no what I'm saying.
