大佬帮忙修修浮动回复脚本

// ==UserScript==
// @name        论坛悬浮回复框
// @description 常用论坛的悬浮回复框，点击固定，再次点击缩回
// @namespace   K
// @include     *
// @version     2.7
// @note        V2.7 忘了关闭按键事件的LOG
// @note        V2.6 更新-修改为仅图标触发展开关闭效果，页面中点击不关闭输入框，避免误操作，输入框中输入内容不影响 & 新增Esc键关闭输入框
// @note        V2.5 依据建议，替换为https的默认图片
// @note        V2.4 修复回复框右键导致的设置框弹出,同时修改左右和上下位置调整
// @note        V2.3 修复鼠标移开的悬浮框显示问题
// @note        V2.2 根据图标和图标位置动态调整悬浮框的宽度
// @note        V2.1 新增，鼠标移动到图标上显示悬浮框
// @note        V2.0 修改为图标触发效果，支持自定义图标，左键(展开-关闭); 右键(设置界面)
