Waterfall view not showing up data for click or scroll events

[pmeenan]

Not sure if it was an issue with that test location, an intermittent issue or something else but I just ran it on the Dulles Thinkpad's and it looks to have navigated correctly: http://www.webpagetest.org/result/160315...de06268e0/

Only change I made was that the execAndWait command had a space after the tab and before "document..." that I removed but that shouldn't cause any issues.
