Is your feature request related to a problem? Please describe.
document.referrer shows "observablehq.com" as the referrer, even for twitter clicked notebooks. This is how iframes are supposed to work. But like document.hash is overridden to passthrough top level page state, I wonder if something similar can be done for referrer.
Describe the solution you'd like
In an ideal world the iframes document.referrer would match the top level document.referrer
