Hi Steve,
That looks very much like
https://github.com/cschwan/sage-on-gentoo/issues/810#issuecomment-3300452963
which is solved by downgrading docutils. Maybe sphinx-inline-tabs does
need some porting to the new docutils.

Perhaps incompatibility between current sphinx and sphinx-inline-tabs.
If so, is sphinx-tabs a solution?
