12967	Need to click undo twice to undo dropping an image	Piotrek Koszuliński		"1. Open http://tests.ckeditor.dev:1030/tests/plugins/uploadwidget/manual/image
2. Drop an image.
3. While it's uploading, click the ""x"" in the notification. Perhaps you can also do some other action, but I observed that clicking notification is ok. Perhaps it's related to focus.
4. Wait for the upload to finish.
5. Click ""undo"".

* Expected: Image should be removed.
* Actual: Nothing happens."	Bug	confirmed	Normal		General	4.5.0 Beta
