Doesn't seem to matter, as far as I can tell. The walkway is part of the same room, though. Strangely the crates on the landing pad, are not, nor are parts of the exterior wall of the swoop gallery; you can see them disappear if you pay attention. But that's a VIS issue, whereas the window issue shouldn't be, for the reasons I specified before.
And in 302 I placed her quite a distance away, basically as far as I could get, clear on the other side of the area, and she was still visible.
