Binding to reflected property

[nazar-pc]

%dom-module(id="cs-icon")
    %template
        %template(is="dom-if" if="[[multiple_icons]]")
            X
        %template(is="dom-if" if="[[!multiple_icons]]")
            Y
    %script(src="script.js")

Polymer(
    'is'                : 'cs-icon'
    properties          :
        icon            :
            reflectToAttribute  : true
            type                : String
        multiple_icons  :
            computed    : '_multiple_icons(icon)'
            type        : Boolean
    _multiple_icons : (icon) ->
        icon.split(' ').length > 1
)

<cs-icon icon="[[icon]]"></cs-icon>

Two issues here:

• eventually neither X nor Y is shown, even though computed multiple_icons is boolean
• while icon property is reflected, attribute is removed during binding to property

No errors in browser console.
When bind as to attribute, everything works as expected.
