i made small demo data attached via datatransfer lost. here code example:

var element = document.getelementbyid('draggable'); element.addeventlistener('dragstart', function (evt) {     evt.stoppropagation();     evt.datatransfer.effectallowed = 'move';     evt.datatransfer.setdata('test', 'some_dummy_data'); } );  var zone = document.getelementbyid('dropzone'); zone.addeventlistener('dragenter', function (evt) {     evt.stoppropagation(); evt.preventdefault();     console.log( '>>>', evt.datatransfer.getdata( 'test' ) ); } );

any appreciated.

"note: security purposes, getdata method can called within ondrop event handler."
