I just checked in IE10, and it looks like we actually do:

4. Allow comments, define that unclosed comments are automatically closed.

Behavior wise, this means that given the following OM:
<div id="parent">
  <div id="child"></div>
</div>

The call: document.querySelector("#parent /* #child");

Returns the parent div successfully. I'm not sure that I'm thrilled about this behavior, but it is what it is...
