Very often you have the file you want to upload somewhere visible in your OS' file browser or even on the desktop. It would improve the "look and feel" a lot if drag and drop would be possible. It is possible with normal clipboard text to type=text, so it shouldnt be a big problem on the UI side. 

I guess the main issue is the error handling when the dropped information is not a valid filename. I'd say this could be handled with a popup similar to the other warnings when sending form-data.

Reproducible: Always

Steps to Reproduce:
1. have a html-form with type=file
2. drag'n'drop a file from desktop or OS-specific file browser to the file-input field

Actual Results:  
a new tab opens showing the file, like it would have been dropped without hitting the form-input

Expected Results:  
entering the filename to the input field as upload file

workaround: open the file-dialog first and drop there

(very cumbersome, but shows up that it can not be a big problem basically)
