           Summary: Range.insertNode() into the middle of a comment
           Product: WebAppsWG
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DOM
        AssignedTo: annevk@opera.com
        ReportedBy: ayg@aryeh.name
         QAContact: member-webapi-cvs@w3.org

Test-case:

data:text/html,<!DOCTYPE html>
<script>
var range = document.createRange();
document.head.appendChild(document.createComment("abc"));
range.setStart(document.head.lastChild, 2);
range.insertNode(document.createTextNode("def"));
</script>

Firefox 12.0a1 and Chrome 17 dev throw HierarchyRequestError.  Opera Next 12.00
alpha splits the comment node, like <!--ab-->def<!--c-->.  I don't have IE
handy to test -- could someone tell me what it does?  The spec says to insert
the new text node immediately before the comment node, so you get something
like def<!--abc-->.

Throwing seems much saner than what the spec says.  is there any reason not to
change the spec to require that, like Gecko/WebKit (and maybe IE too for all I
know)?  I don't know why I specced it this way to start with . . .
