In Firefox version 15 on 2012-08-28 Note: Small SVGs are incorrectly stretched, because percentages in border-image-slice are computed to integers instead of floats (bug 1284797). Until Firefox 47, SVGs without viewport were not sliced correctly (bug 619500). From Firefox 48 until Firefox 49, SVGs without viewport are displayed the same as SVGs with viewport, but if the slices are not exactly 50%, they are incorrectly stretched (bug 1264809). Until Firefox 57, an issue persisted for SVGs without viewport when e10s was disabled (bug 1290782).
