If the upload was stopped because the upload limit for the number of files was reached, then the Upload of files is no longer possible

Actions:

1. Select an empty destination Dataset
2. Choose Folders -> Select a Folder with 2000 Files
3. Choose Files -> Select a File
4. Observation: No "Files limit reached. Please, select less files" Message is displayed
5. Click Upload -> A message is displayed "Files limit reached. Please, select less files" & The files are not uploaded
6. Error: Only the cancel button is clickable (The other buttons are not clickable anymore)
7. Click Cancel
8. Error: The Upload of files is then no longer possible

Expected result: Selecting Files/Folders, Clearing Files and Clicking Upload should be possible after the error message was displayed. Uploading Files should be possible if the File Limit is no longer reached).
