It's a bug, it should be fixed, in my opinion.

It doesn't look nice at all when you're working in a situation where you don't want it.  My test case doesn't represent a great many diverse use scenarios when it comes to drag and drop.

Consider situations where you have something like a file icon in the Mac Finder, where you have an icon at the top and the text label below.  With this bug, recreating that in a browser, the browser puts a big, ugly, semi-opaque square white box around the icon and the label, and you have no obvious way to get rid of it.

I took me hours to figure out why there was a background on the drag image.  When I originally observed the problem it was in a much more complicated web application, and I had no idea where it was coming from, I thought the webkit devs intentionally put the ugly white box in there.  On a hunch, however, I compared my app to another one implementing drag and drop and observed the other app didn't have the ugly white box.

So I went about the tedious process of slowly eliminating various bits of styles until I had isolated the issue.

There is a work-around, and I was lucky to discover that work-around fairly quickly.

These are the kind of things that make web development a nightmare.  It is undocumented, unexpected behavior, and I can't imagine that the scenario of implementing drag and drop inside of a positioned element is really so fringe as to justify not addressing the issue.

I certainly don't think it's a high priority issue in any way, but yes, I believe very strongly it is something that should be fixed.

Thank-you for your time.
