I did a test on windows, and it appears we need to skip clipping if the ORIGINAL width and height are <= 0.
Well, out of curiosity, I've added a quite noisy TRACE to see if there's anything special about those rectangles.
All of those rectangles (the originals, not just scaled versions) have Width = Height = 0, according to debugstr_rectf (so they're simply empty). Chances are it's DrawString(WCHAR*,INT,Font*,PointF&,Brush*), that's really being called here, so Width/Height never really mattered.
