Hints do not appear when using FlowComponent

[andrewliebchen]

The hints, purple boxes around click targets that appear when somewhere other than a target is clicked do not appear when using the FlowComponent.

For example, hints will show here:

layerA = new Layer
layerA.onClick -> print 'Clicked!'

But not here:

flow = new FlowComponent
flow.showNext s.firstScreen

s.nextButton.onClick -> flow.showNext s.secondScreen

Thanks!
