Feed lineage sometimes doesnt render due to timing issue

Description

Feed Lineage may not render due to timing issue with retrieving the data
1. a listener on the page will call the _draw method when the side nav hides.
2. the _draw method expects the `this.feedLineage` object to be defined and populated.
3. if the `getFeedLineage()` isnt returned prior to the side nav listener callback then the JavaScript error will prevent the page from rendering:

the _draw method needs to check if the lineage object is present
