Sortable authors Not Working any more

Hello guys,

We just noticed that the following feature is no longer working:

“Sortable authors: Drag and drop the order of the authors as you’d like them to appear.”

I’ve the latest plugin version and WordPress 4.7, if you drag an author and accommodate it in certain order, after updating/saving the entry, the authors remain on alpha order.

I hope you can take a look at it, I’ll do the same, is there any repo where I could submit a pull request if I come up with a solution?

Thanks in advance!
