How do you drag a tab into another? I cannot seem to be able to reproduce that.

In any case, we likely just have to add a check here: 8dce4e8483/assets/js/dragdrop.js (L30-L35)

I guess that iff there is no file to be uploaded (but something else; say a tab) then event.dataTransfer.files will have a zero-value. We should also probably show an error.

Add check
Add a warning message when a non-file is being dropped

Can confirm, but only when I use another browser (like Chromium) for rushlink, and drag a Firefox tab to Chromium.

Ok. When I drag a Firefox tab into Chrome, Chrome requests for me:

------WebKitFormBoundaryj3RivR1pQwQwmy90
Content-Disposition: form-data; name="file"; filename=""
Content-Type: application/octet-stream


------WebKitFormBoundaryj3RivR1pQwQwmy90--

with these headers:

content-length: 188
content-type: multipart/form-data; boundary=----WebKitFormBoundaryj3RivR1pQwQwmy90

So apparently Chrome does upload a correct form, although with an empty payload for the file field. So I guess that we should check whether the file field is empty, vs being absent.
