Superscript and subscript are not part of commonscript as far as I know (https://spec.commonmark.org/0.31.2/) but it's supported in ggtext element_markdown via ^superscript^ or <sup></sup>. Sadly that's not the case for marquee.
It would be great if marquee also supports superscript and subscript. In the meantime I used UTF-8 variants of superscript numbers (https://www.compart.com/de/unicode/U+00B3)
