Sticky mod key problem

[madprops]

    cyclefocus.key({ modkey, }, "Return", {
        cycle_filters = { cyclefocus.filters.same_screen, cyclefocus.filters.common_tag }
    })

I have this. modkey == "Modkey4" which == super.
I want to use my right hand so that would be the right super and the Enter (return)
This works, the problem is that if I use the right super, cyclefocus sticks (doesn't close when the keys are released).
This also happens if I use right alt instead of left alt for instance, it's not bound to super.
I'm not sure if this is a problem with cyclefocus or awesome or my keyboard.

I have the same problem. I have mod4 mapped to multiple keys. But the popup will only close if I use whatever single key is passed to modifier when calling cyclefocus.cycle(). Passing "Mod4" to cycle does not work, it has to be a single specific key. This is a problem with cyclefocus, I'd say.
