Describe the bug

On macOS in the file selection dialog in addition to selecting a file from the local fs, it is also possible to select media from the user's iCloud library (pictures taken on their phone etc).

When one of these files is selected elk sends a POST request to the media upload API with a blank content, that is the following:

------WebKitFormBoundaryaPwDmoGLFo6pWAuA
Content-Disposition: form-data; name="file"; filename="IMG_8678.jpeg"
Content-Type: image/jpeg


------WebKitFormBoundaryaPwDmoGLFo6pWAuA--

I'm unsure why this happens and as such can't provide much insight into a possible solution.
