<html:meta name="assert" content="A pathLength of zero is a scaling factor of infinity, so a non-percentage startOffset greater than zero becomes +Infinity. Every glyph then falls beyond the end of the path and none of them are rendered. The first text below must therefore draw nothing. The second text is on a path with no pathLength and must draw normally: it is there so that a document which fails to render at all, for a parse error or a missing font, cannot match the reference by accident. Measured on 2026-09-14: Safari 26.4 and Firefox 158 draw nothing for the first text, while Chrome 155 draws about one glyph near the origin, so this test is expected to fail in Chrome."/>
