There is an issue when dragging & dropping multiple folders using resumable.js, on chrome ONLY. It's only upload one of the folders selected. I've tested this case on Firefox/Edge and it's working correctly.
Also I notice that if you upload a folder with any files it will the files that are processed before reading the folder entities.
As I think the issue is only on readeing the directory entites cause if I upload two files its working correclty and also this happen ONLY ON CHROME.
So Can any one help.
