 Thanks for tracking this down. Giorgio: could you have a look at that one?
 I guess the intended behavior is: *if* we need to issue a request due to
 clicking on a `javascript:` link then it should adhere to our first-party
 isolation. That probably means NoScript itself should not issue that
 request as this is treated as a browser internal request which gets put
 onto the catch-all circuit (due to lack of URL bar domain information).

 Does that make sense to you, Giorgio?
