Has Chrome Improperly Implemented The Datatransfer Object?

When I do this in dragstart event: e.dataTransfer.setData('text/plain', 'text'); e.dataTransfer.setData('text/html', 'html'); e.dataTransfer.setData('application/x-bookmark', 'book

Solution 1:

Yes it is a bug in Chrome. See issues 31037 and issue 30240 in the chromium issue tracker (chromium is the open source version of google chrome). I see no other solution than waiting for the bug to be fixed. You can help them fixing it by providing a simple test case.
