Just open it in a separate browser window then? Different windows can have different sizes and get separate buttons in the taskbar.
I guess if you're using Microsoft's ill-advised window grouping feature it would work less well (require more clicks), but breaking websites out into entirely separate programs just so we can have separate windows because Microsoft screwed up the window management functionality seems like a very inefficient workaround.
