After upgrading to v0.5.1 vertical align attribute seems to be removed from paper-dropdown-menu,
before I was doing something like this to control the vertical align, but it isn't working any more:
<paper-dropdown-menu id="typeSelector" halign="{{lang == 'ar' ? 'right' : 'left'}}" selected="{{selectedGroupTypeId}}">
</paper-dropdown-menu>
Any way to do something like this with the updated element?
