Perhaps you simply forgot to adjust the id of the embedded plugin in
<connect>, when moving it to outside the optionset? The following works
for me:

<!DOCTYPE rkplugin>
<document>
        <code file="example.js" />
        <logic>
                <connect governor="x.available"
                    client="levels.variable" />
        </logic>
        <dialog label="Example">
                <varselector id="vars" />
                <varslot id="x" source="vars" label="Select variable"
                    num_dimensions="1" required="true" />
                <embed id="levels" component="rkward::level_select" />
                <valueslot required="true" id="values" label=""
                    source="levels.selector" />
        </dialog>
</document>

(Although, admittedly, the <valueslot> seems to be quirky in that it
does not show in red, initially; I'll look into that.)
