由于 playVideo 中的初始化逻辑是在 setTimeout(..., 1) 中异步执行的，如果视频在播放开始后的极短时间内（例如 1ms 内）被卸载或跳过，restoreVolumeAndUnmount 会先被调用。此时，setTimeout 回调仍会执行，并注册全局双击事件监听器 WebGAL.events.fullscreenDbClick.on(skipVideo)。这会导致内存泄漏，并且在后续双击时可能会触发已销毁实例的 endPerform，引发非预期错误。

建议在注册事件监听器前，先检查 VocalControl 是否仍存在于 DOM 树中（即未被卸载）。

endPerform();
