Testcase (LayoutTests/mathml/presentation/mspace-units.html)

This is a particular case of bug 170229. If you zoom in and out the attached testcase (LayoutTests/mathml/presentation/mspace-units.html) then you see that the relative lengths of bars are inconsistent. This is not the case for the CSS-based reference (LayoutTests/mathml/presentation/mspace-units-expected.html). I believe RenderMathMLBlock's toUserUnits() should multiply some of the values by style.effectiveZoom().
