ScrollableStageText opens keyboard with no focus within Scroller

A ScrollableStageText component within a Scroller will raise the softkeyboard as you scroll. It should only open the keyboard after a full click, not during a scroll gesture.

To reproduce:
1) Install the attached test project on a device.
2) Scroll up and down the screen. Notice that as you scroll, the softkeyboard comes up with no focused input, obscuring your view of the scroller content.
