I've actually tried to do what you requested and found the following enabled...
Most options in the list (if not all) were available, including the delete function...
I did deleted a couple of files for test purposes, looked in the bin and found them there... They were immediately restored such reappearing in the 'Off Line' folder and vanishing from the bin...
So yes, I have found that deletion works, as does restoration... Oh JOY... :-)
Hope that's of interest...
