SkeletonItem white lines on Chrome when zoomed

When viewing SideNav Skeleton/SkeletonItem(s) on chrome when at a 67% or 110% zoom the pseudo-element is calculated less than the height of the div. As noted in the screenshot forcing a height of the pseudo-element to something larger removes the line but a more general solution is probably needed. This causes white lines to appear:

Start by locating the SideNav Skeleton and SkeletonItem components and their pseudo-element styling. Reproduce the white lines in Chrome at 67% and 110% zoom, then inspect the pseudo-element height relative to its containing div. Done means the white lines no longer appear at those zoom levels and the general behavior remains correct.
