Did you try this in RTL? Using "right" does not seem RTL friendly. Is there an
option to use "end" instead of "right"? Given that we already use "right" in
several existing menus, should probably addressed separately (if indeed is
causing an issue).

Just tested with 'ar' and right/left get swapped. It does not recognize
start/end.

yeah, the swapping is fairly unintuitive, but Polymer takes LTR-based
positioning and flips the value based on getComputedStyle(this).dir or
:host-context([dir=rtl]) (one or the other, don't remember)

           <div class="dropdown-content">
             <paper-item id="connect" hidden$="[[device.connected]]">
               $i18n{bluetoothConnect}
