I was able to reproduce as well with this example. Though, I had the easiest time reproducing on a debug build at ToT. I was also able to reproduce the same failure over 11,000 revisions back. So it appears to have been flaky for a while. 

I have updated the expectations to [ Pass Failure ] for the test here:
