I use `disabled=true` to disable a file-drop box but it does not work. I still can drop a file in it.

This file-drop is an Angular 2+ component

```
           <file-drop (click)="file.click()" dropZoneLabel="Drag & Drop file here!" (onFileDrop)="dropped($event)" (onFileOver)="fileOver($event)"
                (onFileLeave)="fileLeave($event)" disabled="true">
            </file-drop>

```
