Currently the intended behavior regarding prevval/prevtype isn't
handled consistently. However, including cursor motion causes events
in `wm->queue` and `wm->eventstate` to behave differently,
where `wm->eventstate` ignores motion (necessary for click detection).
This makes checks from `wm->eventstate` to events in the queue fail.
This reverts 39919e3532,
using the `event.type` instead of it's previous type.
This works as it includes mouse button release events.
