If the Drawer does not cover the whole window, it's possible to tap
outside the dimmer overlay. In that case, next time you tap on the
dimmer, you hit this early return in handleRelease in which
pressPoint.isNull(), so it was not setting touchId back to -1 and doing
the other cleanup/reset tasks. This is a touch release, and touchId
should always be eventually reset after a touch release, regardless of
the code path.
Now QQuickDrawerPrivate::handleRelease() has a QScopeGuard to ensure
that cleanup is done regardless of early returns. That's still not
enough; but when we receive TouchEnd in QPopupPriv::handleTouchEvent(),
it means that _all_ touchpoints are released. So as a fallback for
multi-touch cases, we now ensure that all releases are handled and
stored state is reset, regardless of whether an individual point ID
matches the stored touchId.
