Difference
<text id="revision"> legend every test carries: it renders in a fallback font this
library cannot match, so it is excluded from the comparison entirely rather than failing every test.
Correct rendering requires that each character is rendered. It is not required that a given character be rendered with any particular font; just that it is rendered. It may be rendered with the 'missing glyph' if no glyphs are found in the fonts listed in the content, or in any fallback font that is available.
