Properties from Mixin not recognized

[akc42]

I have a mixin to provide properties to elements for the current user.

When I used these properties in a data binding in an element that extends that mixin and Polymer.Element I am getting a squiggly green line under the property with a hover over error that polymer-ide cannot find the property.

Its also the case that reference to the property in the use of that element at a higher level also causes that use to attract a green line.

I've had the same problem with methods defined in a Mixin not being recognized. Was able to solve it by adding the proper doc-comments to both the Mixin and the Element using the mixin to make the analyzer (and thus the plugin) know about it.

/**
 * My Mixin
 * @polymer
 * @mixinFunction
 */
MyMixin = (superClass) => class extends superClass {
    ...
};

/**
 * My Custom Element
 * @polymer
 * @customElement
 * @appliesMixin MyMixin
 */
class MyElement extends MyMixin(Polymer.Element) {
    ...
}
