Badge appears in wrong position when used with app-drawer

[ghost]

I'm using app-layout with app-drawer / app-drawer-layout and app-header / app-header-layout (see MWE below). The paper-badge is attached to an element inside the app-header. The first time the page is loaded, it briefly appears in the correct position (issue #12), than disappears off the right of the screen, exactly 256px too far to the right, which is the exact size of the app-drawer.

When the screen is resized, it recalculates the position to the correct place.

This does not happen when the app-drawer is retracted and not visible.

I tried running updatePosition() at ready but that did not help. Any ideas how this can be solved?

Here is my MWE:

<template>
<style is="custom-style">
    app-drawer {
      --app-drawer-content-container: {
          background-color: green;
      };
    }
    app-header {
      background-color: yellow;
    }
</style>

  <app-drawer-layout fullbleed>

    <app-drawer slot="drawer">
        <div id="drawerbox">Navigation Drawer</div>
    </app-drawer>

    <div class="container">
      <app-header-layout>
        <app-header id="header" condenses reveals effects="waterfall" slot="header">
           <app-toolbar id="toolbarheader">
              <div main-title id="toolbartitlebox">Title Toolbar</div>
              <paper-icon-button id="discoursebutton" icon="communication:forum"></paper-icon-button>
              <paper-badge for="discoursebutton" label="20" title="20 results"></paper-badge>
           </app-toolbar>
        </app-header>
      </app-header-layout>
    </div>
  </app-drawer-layout>
</template>

In this MWE it would work by placing the badge below and outside the app-drawer-layout. However, in my real code they are in different elements so it no longer works to do that.
One hack that works is to set a setTimeout on the updatePosition():

        ready: function() {
          var self = this;
          setTimeout(function(){
            self.$$('paper-badge').updatePosition();
          }, 100);
        }
