Like CLJ-2089 but for ClojureScript.
Repro, with ClojureScript:
`
$ clj -m cljs.main
ClojureScript 1.10.339
cljs.user=> (def s (sorted-set #{1}))
'cljs.user/s
cljs.user=> (conj s #{2})
Error: Cannot compare #{2} to #{1}
cljs$core$compare (cljs/core.cljs:2380:13)
cljs.core/tree-map-add (cljs/core.cljs:28176:3)
cljs$core$IAssociative$_assoc$arity$3 (cljs/core.cljs:8734:18)
cljs.core/-assoc (cljs/core.cljs:630:17)
cljs$core$IFn$_invoke$arity$3 (cljs/core.cljs:1968:8)

If feasible, this ticket asks that ClojureScript be made to align with the solution in CLJ-2089 (in particular, with making code like 1. )}} fail fast.)
