<hr>
<p>However, in Chrome the checked value that is passed into the `toggleAddCategory` action is inverted, see what is output below after checking/unchecking a checkbox above.</p>
<p style="border:1px dashed black; color:red; padding:10px">
{{#if lastCheckedName}}
	You just <b>{{if lastCheckedState 'checked' 'unchecked'}}</b>
  	{{lastCheckedName}}
{{else}}
	Try checking/unchecking a checkbox above to see this update
{{/if}}
&nbsp;</p>
<p>You can also see this in the console log, where the value of category.get('checked') is flipped in Chrome and FF, but fine in Safari.</p>
