I'm not sure the spec needs to go out of its way to guard against this.
Typically, when writing to a clipboard, you'd clear all the data on the
clipboard before writing the new data; otherwise, you might end up with text
from one window, HTML from another, and a URL from a third. A page that
wanted to stomp on user data could simply do something like
event.clipboardData.setData('text/plain', '').
