Dropzone activity doesn't distinguish between files and selected text

[Inventsable]

On a router view with a fullscreen Dropzone, if you happen to have another element like Input or TextArea and click and drag selected text from within this element, the Dropzone region lights up as if you're dragging a file overtop. This shouldn't happen with file-specific dropping and instead only with the experimental HTML flag in Dropzone, if even then. Releasing the cursor results in the @input and @drop events firing despite the eventTarget being HTML and not a file, which can bubble up to an error on the handler especially if you're expecting a FileList object array.
