File:Meta SVG fonts.svg
When specifying a font family with whitespaces it is recommended to escaping this in quotes, but the SVG rendering engine couldn't interpret this.
(Here the attached file source without quotes [[:file:Meta_SVG_fonts.svg]], one with CSS and one with SVG own property)
Reopened (2017-05-20) as the upstream fix included in librsvg 2.40.10. was only for the CSS property.
T25643: Allow alternative declaration of SVG fonts (font-family="'FontName-Bold'" in addition to: font-family="Font name" font-weight="bold")
Attached:CSS property fixed
SVG attribute not fixed
