Customer has two custom elements with this HTML:

<section id="command-bar-section" class="command-bar slide ng-isolate-scope" ng-transclude="">
    <command-button ng-click="vm.commands.refresh.execute()" scope-id="00C" class="fa fa-refresh ng-scope" data-command-label="Refresh"></command-button>
    <command-button disabled="disabled" ng-click="vm.commands.addEstimate.execute()" ng-disabled="!vm.commands.addEstimate.canExecute()" scope-id="00C" class="fa fa-plus ng-scope" data-command-label="Add"></command-button>
</section>

Customer is trying to verify the enabled/disabled property of the two command-button elements. While recording Test Studio correctly detects the property but during playback it always see's the elements as Enabled and will fail the test when trying to verify the one that is disabled is actually disabled. The log contains:

'11/12/2014 5:03:28 PM' - 'Fail' : 13. Verify 'COMMANDBUTTONTag' is disabled
------------------------------------------------------------
Failure Information: 
~~~~~~~~~~~~~~~
Element enabled state didn't match expected value. Expected: False Actual: True

This is incorrect as the targeted button is actually disabled.

Exact repro steps will be given in the internal bug report.
