radio_group order is reverse when not using a def

[l0rb]

The xml below results in the attached screenshot. When a radio_group does not have a use_def attribute the order of the radios is reverse.

<data>
    <definition name="def1">
        <text size="10" />
    </definition>

    <radio_group name="radio1" x="10" y="10" use_def="def1">
        <radio name="one" label="one" />
        <radio name="two" label="two" />
        <radio name="three" label="three" />
    </radio_group>
    
    <radio_group name="radio2" x="10" y="200">
        <radio name="one" label="one" />
        <radio name="two" label="two" />
        <radio name="three" label="three" />
    </radio_group>

</data>
