[RootCause]:Tochdown executes normally, but touchup fails during hittest
and does not send a touchup event to the script, causing the script to
save an incorrect number of active_touch_points. The application
receives an incorrect event.touches.length, causing a logic error and
preventing the carousel from sliding.
[Solution]:
When hit test on compositor fails, we also need to send the
EmbedderToConstellationMessage::ForwardInputEvent message to
constellation. In the script's handle_touch_event, if it exits early, we
also need to update active_touch_points.
