Expected or Desired Behavior

When running a web part using the knockout template in the SharePoint workbench, it renders the web part.

Observed Behavior

When stepping through the code on init, the web part renders initially, below the loading spinner. Then in the _internalFirstTimeRender method, when this.context.statusRenderer.clearLoadingIndicator(this.domElement) is called, the web part disappears - it is cleaned from the DOM.

I have noticed a difference between the local workbench and SharePoint workbench - 'this.domElement' in the SP workbench contains a '.placeholder' element, whereas in the local workbench it does not.

Steps to Reproduce

Yo a new knockout webpart, (fix the _description bug, and remove all custom properties). Run the web part in the workbench in SharePoint.
