This was a review comment that I forgot to complete before landing Bug 1644160;

“If it’s allowed at all, stamping private fields on an xray retains those values (on the expando object) even if we drop the xray, do a GC, then get the same xray wrapper again.”

While I am at it, I should also check for the private-field version of Bug 1404107.
