I think what happened is that the problem \mbox tries to solve is
solved in a slightly better way by other commands like \text. As a
result katex only implemented the better solution. Your reasoning to
use \mbox instead \of text might be a reasonable argument for keeping
the current behavior in Sage, despite this annoying katex situation.
Regarding CoCalc, yesterday I added an alias so that now our katex
rendering works with \mbox (it just sets \mbox to \text), so these
sage manifolds notebooks all look fine now.
