When adding an item through the Autocomplete dragtable widget, if user fill the textfield with random string it will accept the value and insert an empty record / row on the table, after some debug I have found that there is any check or validation if the user has filled the random string or non existent entity.
1. Login as admin
2. Navigate to Web -> Structure -> Entity Queue. Click view Subqueues of any available queue
3. Click Edit item.
4. Click Add item typing anything in the autocomplete field. One empty entry is added.
