Fix first swipe after exiting AOD

I can't explain what changed, but the NPVC height
calculation is no longer getting updated when exiting
AOD. This leads to the incorrect height being used
in a swipe calculation that is off by quite a bit,
and preventing the drag from being processed and
sending events on the first swipe only.

Test: manual - exit AOD, and swipe up
