0.9 preview fails with composite action

With such simple setup as shown above, the right stick on the gamepad works fine.
However negative keys are never calling canceled / seems like the release button is never detected.
Leading an object forever moving after pressing a/s/d or arrows other than up.

Is filing a bug ticket for a preview package the same as a normal unity bug ticket or is there a different process ?
(Or maybe I'm just doing something wrong ...)

Edit: I created the following ticket: 1171733
