Google Search not in TO

I am now looking at a Google search tab that isn't appearing in TO. I've scanned, looked at the location it should appear in, and even searched for the keywords in the TO window. I opened several windows as children from this search page, and they appear just fine, but they appear as children to the search window's parent.

I haven't seen this behavior before.

I don't know if this is related to the phantom tab bug I posted about a while back - a bug I still experience regularly.
