Taking a profile of the same page with gecko profiler does show the function names. See also bug 1265526.

I'm going to mark this as P2. But I'm also going to cross-reference this with perf.html to make sure we get this right there. I think some assumptions about the data we get back are wrong here. This is a great test case.
Oh, and thank you for filing this, this is a great report.
