When an element's border width is computed from EM, should the
computed border width include fractions of a pixel?

IOW, when calling:-

 getComputedStyle(el, '').borderWidth,

- is the return a float or an int?

Furthermore, should the precision, if rounded down for rendering, be
preserved? If it is preserved, it would seem that three border-widths
of 33.3px would add up to 100px, and that this is where the element
should appear, and that measurement should be reflected in
getBoundingClientRect.
