Repro:

1. Add <input type=file> to a page
2. Drag&drop a folder onto it

Expected: Drop-action is not supported
Actual: Drop permitted, "change" event fires

3. Inspect the HTMLInputElement's files collection

Expected: files collection contains useful File elements
Actual: files contains a single File

* Has the name of the folder
* Has a size e.g. 4096
* If you attempt to read the content with a FileReader the operations fails with name: "NotFoundError", message: "A requested file or directory could not be found at the time an operation was processed."

NOTE: This also applies to drop targets via DataTransfer.files
