What steps will reproduce the problem?
(1) Call console.log() from within a blackboxed script
(2) Open Console sidebar and expand to see the file producing the log

What is the expected result?
Sidebar should respect blackboxing and show the log as originating from the nearest un-blackboxed parent file, or perhaps <other> if there is none

What happens instead?
Sidebar shows the url of the blackboxed file
