Please fix nits in the test before you land.

It seems like we have the same problem in LabelsNodeList and others that can be rooted at the document node.
We might want to fix them as well in a follow up patch.

Why is the value "rbarrval1"? Can we use some other human-understandable value instead?

Ditto.

Thanks rniwa, I did not see that commit failed, I was not available, it was 2AM already.

[Ryosuke Niwa]

On my second thought, this patch doesn't fix the bug completely in some edge cases.

[Ryosuke Niwa]

I'm rolling out the patch because the fix is incorrect.

[Ryosuke Niwa]

Apparently sheriffbot can't roll out this patch. I'll file a new bug and manually revert this change and make the right fix.
