Has Hackney added the update this is waiting on? I'd love to see this feature merged!

Would still love to see this make the 1.0.0 release cycle!

Would definitely like to see this added! :+1:

I would also love to have proper tests project set up with best practices baked into the boilerplate!

Yes! I can path to it and everything performs as expected once open, it's only the drag and drop functionality that doesn't work.

Another diagnostic point is that I'm using a Surface Book, if the presence of touch + pen input interferes with your drag and drop in some way?

Yes! If I launch Tail Blazer from an Administrator cmd prompt Drag and Drop doesn't work but non-Administrator did allow me to drag and drop.

This article is quite old but seems to explain the the issue. http://blogs.msdn.com/b/patricka/archive/2010/01/28/q-why-doesn-t-drag-and-drop-work-when-my-application-is-running-elevated-a-mandatory-integrity-control-and-uipi.aspx It seems to be a security feature but you can explicitly opt-in to allowing specific messages through...

There are libraries which only perform the syntax highlighting like [prism](https://prismjs.com/index.html) or [highlight.js](https://highlightjs.org/) if the overhead of CodeMirror's whole stack isn't desirable.

I've also been receiving this issue randomly after working on in my project with the dev server running for a few hours.
