UPDATE: Looks like this will get fixed in the next release according to a comment on Steve’s blog.
Not only did he encounter the bug, he went through the hard work to dig into the source of the bug right down to the line of code and proposes a fix. How is that for constructive criticism?
Unfortunately, he hasn't received any response from the Atlas team (at the time of this posting) regarding whether or not they recognize this as a bug and if they will fix it. He subsequently filed an official bug report at Microsoft Connect.
This is not some arcane bug, so you may get bit by it as well if you use any browser extension such as CoComment with Atlas.
