Manual sorting of Notifications by dragging does not work many times

[halig]

I have tried several browsers.

By dragging notifications, sometimes they stay where you have released the mouse and sometimes they don't. And I've tried all locations, browsers, cookies, restarting, etc.

I am a computer tech and ex-programmer. There is a bug. The logical thing is that there is a way to sort or search, because having to sort manually is something from the pleistocene. At least it should work. Thanks
