Hi,

Selecting a chunk of text from a word document opened in Microsoft word, dragging the selection, then dropping it in a contentEditable div results in nothing being actually dropped.
Here is a codesandbox reproduction sample: https://codepen.io/hamza0867/pen/ZErRJbp?editors=1111 

Thank you

I can reproduce this with latest Word (16.60). Works with TextEdit.

Guessing that Word may be providing a promise instead of full data in the drag pasteboard, I don't remember any code in WebKit to support that.

There is a promise reading codepath in WebKit, but it only works in the context of promised file URLs (by calling into `-receivePromisedFilesAtDestination:options:operationQueue:reader:`). It seems like we'll need to generalize this to work with rich text data.
