There is probably overlap here.

Microsoft differentiates the dataTransfer and clipboardData objects. The former
is with respect to event objects and the latter with respect to the window
object (see first sentence of "Data Transfer Objects" at
http://msdn.microsoft.com/en-us/library/ms537658%28VS.85%29.aspx).

It sounds like WebKit uses the same pipeline for handling this kind of
functionality, but I have not checked. Though, it wouldn't surprise me if they
did at some point since these objects share a common goal of transferring data.

For your reference, this test case tests the issue with respect to
event.dataTransfer. The test case
<http://trac.webkit.org/browser/trunk/LayoutTests/editing/pasteboard/crash-accessing-clipboardData-types.html?rev=49513>
seems to test with respect to window.clipboardData (but it even looks like
window.clipboardData == event.clipboardData == event.dataTransfer - but I
haven't confirmed this).

We can remove the test case if you want. What are your thoughts?
