How to have multiple views in wingle window mode using GIMP?

I'd like a real-time preview while editing icons in GIMP.

I know that you can press View > New View to get a real-time preview window, however in single window mode gimp puts the preview in a separate tab as if it was another image. This is obviously no good as now I have to go and click on the tab to see the preview, which would take longer than just zooming out.

I'd prefer to stay in single window mode, so is it possible to tell gimp to put the new view in a second window?
