Modifying styles through automation truncates "spacing" field to int

[TheFluff]

script_name = "Style Copy"
script_description = "Duplicates a style."
script_author = "Lexica-chan"
script_version = "1.0"

function do_style_copy(subs)
    local style = nil
    local stylepos = nil

    for i = 1, #subs do
        if subs[i].class == "style" then
            stylepos = i
            style = subs[i]
            break
        end
    end
    
    style.name = style.name .. " (Copy)"
    subs[-1 * stylepos] = style
    
    aegisub.set_undo_point(script_name)
end

aegisub.register_macro(script_name, script_description, do_style_copy)

The above code should do nothing to the style, but if the spacing field is noninteger, it gets truncated.
