What steps will reproduce the problem?
(1) Run the attached layouttest.

What is the expected result?
The test should fail (assertion not met)

What happens instead?
The test times out instead, if you change the button to left or remove the pointerMove action, then it fails as expected. seems like the callback is never called.
