We have RadUpload which has MaxFileSize limited to 10MB. If I only try to upload document everything works OK and the document is not uploaded. However, if I select the file which is open in editor, then close the editor and press upload, file is uploaded, even if size is bigger than 10MB

Steps to reproduce bug:
1. Open a file, which is bigger than max allowed size in editor (i.e. on MSWord)
2. Select the file in RadUpload - an exception is thrown to indicate the file is used by another process 
3. Close the editor
4. Press upload - the file is uploaded even though its size is bigger than the allows file size
