Upload event doesn't work

[ghost]

Upload must start after drop event, but it doesn't.
I changed the code

reader.onloadend = !opts.beforeSend ? send : function (e) {
opts.beforeSend(files[fileIndex], fileIndex, function () { send(e); });
};

to this one

reader.onloadend = !opts.beforeSend ? send : function (e) {
opts.beforeSend(files[fileIndex], fileIndex, function () { send(e); });
send(e);
};

and it works for me.
Please check this moment, and if there is more efficient solution, do and commit it please. Thank you.

You must call done(); in your custom beforeSend hook.
See the comments in the example.
