The following testcase will work with Controls scrum b316, but fail with b317.

On a Mac, simply place the cursor over the black rectangle, and
use the tracker pad to send a ScrollEvent (two-findered drag).
With b316 you will see the printlns from the handle(), with b317
you won't.

B316 & B317 can be found at :
