GM_registerMenuCommand not trigger click callback in firefox browser

[WhiteSevs]

Expected Behavior

期望修复注册顺序和点击回调无效的问题

Actual Behavior

注册菜单 => test1->test2->test3
↓
卸载菜单
↓
注册菜单 => test2->test3->test1

问题：在最后注册完菜单完成后，菜单顺序不同，且菜单test2和test3的点击事件不触发，只有test1的点击事件触发
该测试在Edge+TamperMonkey BETA 5.1.6193下又是正常的
