If you drag the image file from the Windows Explorer oder the macOS finder info.magnolia.dam.focal.field.FocalDamUploadField#fireUploadEvent is not invoked.

The cause is that in the case of dragging the image to the upload field the event com.vaadin.ui.Upload.SucceededEvent within com.vaadin.ui.Upload is not fired.

Since we adopted the approach in a custom logic which is even more important than the DAM Focal feature it's a major issue to us.

Is there any support you can give if this is a known issue and it will be fixed by you or Vaadin?
