use multiple finger pan，sometimes when all fingers leave screen，I found “hammerManager.input.store” length is not 0

the demo

const hammerManager = new Hammer.Manager(dom);
let lastPanEndEvent = null;

  // five pan，one finger｜two finger ｜ three finger...
  const panArray = [1, 2, 3, 4, 5].map(
    pointers =>
      new Hammer.Pan({
        event: `pan${pointers}`,
        threshold: 4,
        pointers,
        direction: Hammer.DIRECTION_ALL,
      })
  );
  hammerManager.add(panArray);

  hammerManager.on('pan1start pan2start pan3start pan4start pan5start', evt => {});
  hammerManager.on('pan1move pan2move pan3move pan4move pan5move', evt => {});
  hammerManager.on('pan1end pan2end pan3end pan4end pan5end', evt => {
    if (evt.type === 'pan1end' || evt.type === lastPanEndEvent) {
      if (hammerManager.input.store) {
        hammerManager.input.store = [];
      }
      end();
    }
    lastPanEndEvent = evt.type;
  });
