When the items are dropped on another tree item in the same tree, your DataTransferItem objects
will be preserved. Use the recommended mime type for the tree (application/vnd.code.tree.<treeidlowercase>) to add
tree objects in a data transfer. See the documentation for DataTransferItem for how best to take advantage of this.
To add a data transfer item that can be dragged into the editor, use the application specific mime type "text/uri-list".
The data for "text/uri-list" should be a string with toString()ed Uris separated by newlines. To specify a cursor position in the file,
