Content of Select Media window disappeared after uploading image

[maddisondesigns]

Issue Overview

I added an image block and after clicking the Add from Media Library button, I simply dragged an image to the Select or Upload Media popup window. The complete contents of this popup window then disappeared.

Steps to Reproduce (for bugs)

1. Insert image block
2. Drag image onto Select or Upload Media popup window

Expected Behavior

I expect the popup window to show the uploaded image, not clear the whole content of its content

Current Behaviour

Content in Popup window randomly disappears

Firefox Quantum 57.0.4 (64-bit)
Gutenberg 2.0.0
WordPress 4.9.2
No other plugins activated

Thanks for the report, @maddisondesigns. I've been able to replicate with the steps you provided:

Interestingly, the image did end up in the post:

It seems like there's a drag-in-drop zones conflict.
