$event.dataTransfer.dropEffect = 'copy' not getting applied

[boustanihani]

I have an area where I can drag and drop files to:

<div @dragover.prevent=" $event.dataTransfer.dropEffect = 'copy' "
    @drop.prevent=" filesSelected($event.dataTransfer.files) "
    @change.prevent=" filesSelected($event.target.files) ">
    <input type="file" id="files" name="files[]" multiple />
</div>

The drop and the change events are getting fired as they should, only the dropEffect = 'copy' is not getting applied.

How do you know it's not being applied?

Here I don't see any thing that would change based on that value.

So what makes you think it's not being applied?

It was getting applied, I just thought something is wrong because on windows you also see the number of the files (above the mouse cursor), but on linux you don't..
