    This will display identical on Ladybird and Chromium (131.0.6778.85) (centered), but left-aligned on Firefox (129.0.2)
    Guessing Firefox has it right; no reason why missing height should align center (see standalone.svg where all left align)
    Suggestion: not a priority, since it works the same as chromium
    Likely a result of settings in Default.css
