Details

This doesn't get a JS pseudostack for some reason. http://bit.ly/2sKyVHK Looks like most of the time is spent in GetCaseIndependentLetters(). Note that I'm not certain if this time falls inside the span of the time that the test suite measures directly.
See bug 1373195. This shows up as particularly bad with Callgrind, so it's interesting you saw it in a "real" profile. I wasn't sure if Callgrind made it seem worse than it actually is.
