I recall moving focus for paste events in order to figure out what is being
pasted. I believe this is common in WYSIWYG editors; a new element is
created and focus is moved to that element, then the paste occurs, then the
element is inspected for the content and the editor does whatever it needs
to (like cleaning up junk from pasted Word documents). Obviously if there
was a cleaner way to get the contents, like Microsoft APIs for accessing
the clipboard, then this wouldn't be needed.
