There is no automatic rescaling in this example. Transformations only happen in SVG when: 1) There is a 'transform' attribute on an element 2) There is a 'viewBox' (or maybe 'preserveAspectRatio') attribute on an element In particular, an 'svg' element does NOT scale the coordinate system unless there is a 'viewBox' attribute. All that the width/height attributes do in this example is establish an automatic clipping path due to the default of overflow:hidden, but the rectangle is fully within the clipping path so the clipping path has no effect. In this test case, the only 'transform' attributes present only do translations (i.e., shift the coordinate system in X and Y without scaling) and there are no 'viewBox' attributes. Since there are no scale transformations, each rectangle should be 75px by 75px.
