Make scrollParentContainer() more robust as it's used in a timeout callback

Browse source 
Example exception:

Exception in setTimeout callback: TypeError: Cannot read property 'parentComponent' of null
at constructor.scrollParentContainer (cardDetails.js:77)
at cardDetails.js:190

Probably there is a better fix for this.
