BUG：在任意位置使用手势（下滑）向上滚动都会触发onRefresh

预期：滚动到顶部后再下滑才触发onRefresh

import { PullRefresh, Toast } from "@arco-design/mobile-react";
import React from "react";

const onRefresh = () =>
  new Promise((resolve) => setTimeout(resolve, 100)).then(() => {
    Toast.info(
      `Refresh successfully @${new Intl.DateTimeFormat("zh-CN", {
        timeStyle: "medium",
      }).format(new Date())}`
    );
  });

const data = Array.from({ length: 20 }, (_, index) => `index: ${index}`);

export default function PullRefreshDemo() {
  return (
    <PullRefresh onRefresh={onRefresh}>
      {data.map((item) => (
        <div key={item} style={{ paddingBlockEnd: 50 }}>
          {item}
        </div>
      ))}
    </PullRefresh>
  );
}

但时当给.arco-pull-refresh-content或.arco-pull-refresh添加高度样式后行为正常

.arco-pull-refresh{
  height: 100vh
}
